Chemistry has been defined as the science that is concerned with the composition, properties, and structure of matter and with the ways in which substances can change from one form to another. But this definition is too broad to be useful. Chemistry isn't the only science that deals with the composition and transformations of matter. Matter is also composed of complex materials like animal hides which are transformed by craftspeople into beautiful leatherwork, or wood which is transformed into furniture, or cotton which is transformed into different grades of cloth. These are normally considered the subject of materials scientists or even consumer scientists. Chemists are unique because they understand or explain everything, even the subjects of importance to consumers in everyday life, in terms of the properties of just over 100 kinds of atoms found in all matter, and the amazing variety of molecules that are created by forming and breaking bonds between atoms. So chemistry is defined by its approach, not its subject matter . Chemistry explains or understands any subject in terms of the properties of atoms and molecules.

Chemistry can help craftspeople create more functional or interesting objects, or help consumers evaluate fraudulent or unsafe products. Has a cashier ever used a yellow pen to check if your paper money is counterfeit? The yellow marker is iodine (I 2 , combined with I - to make I 3 - ), and if it turns blue/black, this indicates a counterfeit bill. The reaction is the classic iodine test for starch. When iodine enters the helical starch molecule as shown in the figure, it turns blue/black.

The ribbon-like starch molecule is made up of glucose molecules, shown in the figure, linked together. But to understand why this detects counterfeit money, we need to know more about paper .

"What's That Stuff" [2] is a regular feature of an American Chemical Society publication that gives examples of how chemistry is used to enrich everyday life. It tells us that Paper [3] is made by soaking plant fibers in water, then matting, pressing, and drying them. American paper money is made from a mix of cotton and cotton gin trash (75%) and flax waste (25%). Ordinary paper uses wood fibers which need to be bleached and starched to have the same quality surface, so they turn black when marked with the cashier's pen, while marks remain yellow on legitimate bills.

What holds paper together? Papermaking is an old art, dating from ancient Egypt where papyrus reeds from the Nile were used. It's a common hobby or profession that traditionally uses a process called retting to remove all but the cellulose from plant fiber. The cellulose is beaten in a Hollander to produce wet pulp. When it's pressed, the cellulose molecules form intermolecular bonds between the oppositely charged hydrogen and oxygen atoms shown in the figure.

in "natural foods" are no different than synthetic molecules made in the lab; they are both "chemicals" when understood in terms of their molecular structure or properties. When people speak of "chemical free" products, they usually mean that the material is found in nature and so was not designed by a chemist, even though the molecules designed by chemists are identical. Chemists often say 'everything is a chemical" because it is possible to understand everything in terms of molecular properties.

Chemistry is a discipline that falls somewhere between physics and biology in terms of scope. It is also referred to as the “core science” since it provides a fundamental framework for understanding both basic and applied scientific disciplines. Chemistry, for example, explains aspects of plant chemistry (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties of lunar soil (cosmochemistry), how medications work (pharmacology), and how to collect DNA evidence at a crime scene (criminology) (forensics).

Chemistry is a discipline of science concerned with the study of matter, including its structure, composition, and changes that occur when it is exposed to various situations. As a result, chemistry not only investigates the qualities of matter, but also how and why it changes.

Chemistry is like our everyday lives unseen behind-the-scenes wizard, quietly influencing everything around us in a myriad of ways. It is found in the air we breathe, a mixture of gases that chemists comprehend and control for a variety of uses, including carbon dioxide for photosynthesis in plants and oxygen for human survival. Every time you prepare food, chemistry is at work, changing the taste, texture, and appearance of raw components to create delectable dishes.

Below are the importances of chemistry in various fields:

Chemicals are the fundamental components of everything. Chemical molecules make up all food, including carbs, vitamins, lipids, proteins, and fiber, which are all safe and often desirable.

Food Additives

Chemicals have an important part in the manufacturing and preservation of food. Food preservation chemicals have tremendously aided in the preservation of food for a longer duration. Cans of food additives, flavourings, and nutritional supplements can all contribute to improve the quality and quantity of meals.

Chemistry has provided the globe with vital fertilizers, herbicides, insecticides, and fungicides to aid in the production of healthy and nutritious crops, fruits, and vegetables. Urea, calcium superphosphates, ammonium sulphate, and sodium nitrate are all significant fertilisers.

Medicines or pharmaceuticals are chemical substances that are used to treat diseases and relieve pain. Chemistry has made significant contributions to health care. Chemistry, for example, aids in the manufacture and application of surgical materials (sutures, artificial skin, and sterile materials).

For analysis, clinical laboratory tests employ a wide range of chemical procedures and substances.

Some important drugs in chemistry-

• Analgesics are pain relievers that are used to treat a variety of ailments.
• Tranquilizers are medications that are used to treat mental illnesses. Take, for instance, tension.
• Antiseptics are used to destroy or prevent the growth of microorganisms on the skin, wounds, and cuts.
• Disinfectants- These are chemicals that destroy microorganisms but are dangerous to humans.
• Antibiotics- Antibiotics are chemical substances produced by some microorganisms that can be used to kill bacteria that cause infections.
• Antacids- These are the compounds that are used to eliminate excess acid from the stomach and increase the pH to a healthy level.

In our daily lives, we use lotions, fragrances, talcum powder, and a variety of other cosmetic goods. All of these items are developed in laboratories using chemicals for our health and skin. All cosmetic items, from babies to adults, are made up of chemical components.

As a result, chemistry is important in maintaining the pH of our skin, keeping it healthy, and removing any marks.

Green chemistry contributes to environmental protection by monitoring, protecting, and enhancing the conditions in which we live, such as air, water, and soil. Many methods and strategies have been created to ensure that all types of pollution in the environment are measured and prevented from depleting.

To make the air cleaner, many non-polluting fuels and compounds that can easily absorb contaminants from the air are being researched and tested. The replacement of CFC in refrigerators is one such example.

For interpreting health impacts, controlling emissions, and creating pollution-reduction devices, chemistry gives a complete understanding of contaminants.

Chemists test the water and soil for contamination on a regular basis and offer pollution results as well as long-term prevention for ecological balance and human health.

Soaps are sodium and potassium salts of fatty acids with greater molecular weights, such as stearic acid, palmitic acid, and oleic acid. Sodium salts of long-chain alkyl hydrogen sulphates or sodium salts of long-chain alkyl benzene sulphonic acids are commonly used as detergents.

Detergents and soaps are used for washing, cleaning, and bathing, among other things. The saponification method is used to make them in chemical companies. As a result, chemistry plays a significant role in the development of molecules, chemicals, and procedures for the production of soaps and detergents.

Wool, silk, jute, cotton, flax, glass fiber, polyester, acrylic, nylon, and other raw materials are used in the textile industry to create usable items such as clothing, bags, carpets, furniture, towels, nets, and so on. Throughout the

Raw materials go through a number of chemical procedures during which cleaning and smoothing reagents are employed to clean and smooth the fabric.

Other chemical processes including dyeing, bleaching, scouring, printing, and finishing are also involved. In addition, chemists seek to increase a product’s quality.

Chemical items such as bricks, cement, pipelines, and other building materials all play an essential part in the quality of construction. Floor and wall tiles are constructed of heat-resistant polymers that also add strength to the structure.

Ceiling and roof materials are also designed to be heat resistant and give cooling to the structure. All of the pipes and switches are composed of polymers, which are both heat and stress-resistant.

As a result, chemistry enabled the use of all of these goods for the development of structures and people’s lives.

Fuels are the sole thing that allows us to travel by land, sea, and air nowadays. Petrol, diesel, LPG, CNG, kerosene, oils, and other fuels are all obtained through sophisticated refining procedures from harsh oil found beneath the Earth’s crust.

Petrochemistry is a discipline of chemistry concerned with the study of petrochemical processes and how to use fuels in a way that is both pollution-free and long-term.

Batteries power our automobiles, electronic devices such as watches, laptops, mobile phones, and a variety of other power storage applications.

The electrochemistry concept governs the operation of batteries. Chemical energy is stored inside a battery and is transformed to electric energy through electrochemical processes.

Chemistry plays a crucial role in agriculture, contributing significantly to the field’s productivity and sustainability. It enables farmers and researchers to develop innovative solutions that address the challenges of feeding a growing global population while minimizing environmental impact. Through chemistry, we can optimize soil health by analyzing and adjusting nutrient levels, ensuring that crops receive the necessary nutrients for healthy growth.

Pesticides and herbicides, formulated using chemical principles, help protect crops from pests and weeds, reducing crop loss. Additionally, chemistry is involved in the development of fertilizers that enhance crop yields, ensuring a more abundant and consistent food supply. Furthermore, the study of chemistry aids in developing sustainable farming practices and reducing the environmental footprint of agriculture by promoting the responsible use of chemicals. In essence, chemistry is an indispensable tool for modern agriculture, facilitating increased food production, improved resource efficiency, and environmental stewardship.

TNT, RDX, HMX, gun powders used in bullets, and other explosives used in conflicts are all chemical compounds. It was the chemistry that allowed these chemicals to be used during the war. Nuclear weapons, which have become more well-known in recent years, are also chemical chemicals.

The important articles on uses & applications of chemistry in everyday life are provided in the table below:

In the CBSE Class 12 Chemistry curriculum, the “Chemistry in Everyday Life” unit is designed to highlight the connections between chemical principles and their applications in daily life. This unit covers various topics that explain how chemistry affects our health, environment, and various industries.

MEDICINES CHEMISTRY IN EVERYDAY LIFE Done by Vishal Rajesh Lakhiani 12 - O

INTRODUCTION • Drug – A chemical of low molecular mass (100 – 500u) which interact with macromolecular targets and produce a biological response. • Medicine – When the biological response produced by a drug is therapeutic and useful, then the drug is called a medicine.

CLASSIFICATION OF DRUGS

ON THE BASIS OF PHARMACOLOGICAL EFFECT • This classification is based on the pharmacological effect of the drugs. It is useful for doctors because it provides them the whole range of drugs available for the treatment of a particular type of problem. • For example, analgesics have pain killing effect, antiseptics kill or arrest the growth of microorganisms.

ON THE BASIS OF DRUG ACTION • It is based on the action of a drug on a particular biochemical process. • For example, all antihistamines inhibit the action of the compound, histamine which causes inflammation in the body. There are various ways in which action of histamines can be blocked.

ON THE BASIS OF CHEMICAL STRUCTURE • It is based on the chemical structure of the drug. Drugs classified in this way share common structural features and often have similar pharmacological activity. • For example, all sulphonamides are derivatives of

ON THE BASIS OF MOLECULAR TARGETS • Drugs usually interact with biomolecules such as carbohydrates, proteins, lipids and nucleic acids. These are called target molecules or drug targets. • Drugs possessing some common structural features may have the same mechanism of action on targets. The classification based on molecular targets is the most useful classification for medicinal chemists.

ENZYMES&RECEPTORS

ENZYMES • Enzymes are biological catalysts. Most are proteins. (A few ribonucleoprotein enzymes have been discovered and, for some of these, the catalytic activity is in the RNA part rather than the protein part. Link to discussion of these ribozymes.) • Enzymes bind temporarily to one or more of the reactants of the reaction they catalyze. In doing so, they lower the amount of activation energy needed and thus speed up the reaction.

ENZYME ACTION • Most of these interactions are weak and especially so if the atoms involved are farther than about one angstrom(10-10m) from each other. So successful binding of enzyme and substrate requires that the two molecules be able to approach each other closely over a fairly broad surface. Thus the analogy that a substrate molecule binds its enzyme like a key in a lock. • This requirement for complementarity in the configuration of substrate and enzyme explains the remarkable specificity of most enzymes. Generally, a given enzyme is able to catalyze only a single chemical reaction or, at most, a few reactions involving substrates sharing the same general structure.

COMPETITIVE INHIBITION • The necessity for a close, if brief, fit between enzyme and substrate explains the phenomenon of competitive inhibition. • One of the enzymes needed for the release of energy within the cell is succinicdehydrogenase. • It catalyzes the oxidation (by the removal of two hydrogen atoms) of succinic acid (a). If one adds malonic acid to cells, or to a test tube mixture of succinic acid and the enzyme, the action of the enzyme is strongly inhibited. This is because the structure of malonic acid allows it to bind to the same site on the enzyme (b). But there is no oxidation so no speedy release of products. The inhibition is called competitive because if you increase the ratio of succinic to malonic acid in the mixture, you will gradually restore the rate of catalysis. At a 50:1 ratio, the two molecules compete on roughly equal terms for the binding (=catalytic) site on the enzyme.

FACTORS AFFECTING ENZYME ACTION

FACTORS AFFECTING ENZYME ACTION • The activity of enzymes is strongly affected by changes in pH and temperature. Each enzyme works best at a certain pH (left graph) and temperature (right graph), its activity decreasing at values above and below that point. Examples: • the protease pepsin works best as a pH of 1–2 (found in the stomach) while • the protease trypsin is inactive at such a low pH but very active at a pH of 8 (found in the small intestine as the bicarbonate of the pancreatic fluid neutralizes the arriving stomach contents).

REGULATION OF ENZYME ACTIVITY • Several mechanisms work to make enzyme activity within the cell efficient and well-coordinated. • Anchoring enzymes in membranes: • Many enzymes are inserted into cell membranes, for examples, • the plasma membrane • the membranes of mitochondria and chloroplasts • the endoplasmic reticulum • the nuclear envelope • These are locked into spatial relationships that enable them to interact efficiently.

INACTIVE PRECURSORS • Enzymes, such as proteases, that can attack the cell itself are inhibited while within the cell that synthesizes them. For example, pepsin is synthesized within the chief cells (in gastric glands) as an inactive precursor, pepsinogen. Only when exposed to the low pH outside the cell is the inhibiting portion of the molecule removed and active pepsin produced.

FEEDBACK INHIBITION • If the product of a series of enzymatic reactions, e.g., an amino acid, begins to accumulate within the cell, it may specifically inhibit the action of the first enzyme involved in its synthesis (red bar). Thus further production of the enzyme is halted.

PRECURSOR ACTIVATION • The accumulation of a substance within a cell may specifically activate (blue arrow) an enzyme that sets in motion a sequence of reactions for which that substance is the initial substrate. This reduces the concentration of the initial substrate.

ALLOSTERIC SITES • In the case of feedback inhibition and precursor activation, the activity of the enzyme is being regulated by a molecule which is not its substrate. In these cases, the regulator molecule binds to the enzyme at a different site than the one to which the substrate binds. When the regulator binds to its site, it alters the shape of the enzyme so that its activity is changed. This is called an allosteric effect. • In feedback inhibition, the allosteric effect lowers the affinity of the enzyme for its substrate. • In precursor activation, the regulator molecule increases the affinity of the enzyme in the series for its substrate.

Graph showing velocity of reaction with concentration of substrate in the presence of an enzyme

The Effects of Enzyme Inhibitors • Enzymes can be inhibited • competitively, when the substrate and inhibitor compete for binding to the same active site or • noncompetitively, when the inhibitor binds somewhere else on the enzyme molecule reducing its efficiency. • The distinction can be determined by plotting enzyme activity with and without the inhibitor present.

COMPETITIVE INHIBITION • In the presence of a competitive inhibitor, it takes a higher substrate concentration to achieve the same velocities that were reached in its absence. So while Vmax can still be reached if sufficient substrate is available, one-half Vmax requires a higher [S] than before and thus Km is larger.

NON-COMPETITIVE INHIBITION • With noncompetitive inhibition, enzyme molecules that have been bound by the inhibitor are taken out of the game so • enzyme rate (velocity) is reduced for all values of [S], including • Vmax and one-half Vmax but • Km remains unchanged because the active site of those enzyme molecules that have not been inhibited is unchanged.

DRUG-RECEPTOR INTERACTIONS • Receptors are proteins that are crucial to body’s communication process. • The vast majority of drugs show a remarkably high correlation of structure and specificity to produce pharmacological effects. Experimental evidence indicates that drugs interact with receptor sites localized in macromolecules which have protein-like properties and specific three dimensional shapes. A minimum three point attachment of a drug to a receptor site is required. In most cases a rather specific chemical structure is required for the receptor site and a complementary drug structure. Slight changes in the molecular structure of the drug may drastically change specificity.

DRUG INTERACTION WITH RECEPTOR SITE • A neurotransmitter has a specific shape to fit into a receptor site and cause a pharmacological response such as a nerve impulse being sent. The neurotransmitter is similar to a substrate in an enzyme interaction. • After attachment to a receptor site, a drug may either initiate a response or prevent a response from occurring. A drug must be a close "mimic" of the neurotransmitter.

AGONIST & ANTAGONIST • An agonist is a drug which produces a stimulation type response. The agonist is a very close mimic and "fits" with the receptor site and is thus able to initiate a response. • An antagonist drug interacts with the receptor site and blocks or depresses the normal response for that receptor because it only partially fits the receptor site and can not produce an effect. However, it does block the site preventing any other agonist or the normal neurotransmitter from interacting with the receptor site.

The Wonders Of Chemistry Around Us

List of wonders of chemistry in everyday life, introduction.

The word Chemistry makes us think of Chemicals, beakers, test tubes, burners, and an evil scientist working on a power potion! Jokes apart, we are surrounded by the magic of Chemistry. We use so many things daily which are the contribution of this subject to make our life better and easier. There is Chemistry in everyday life.

The wonders of Chemistry are in the brilliant chemical reactions that happen in the human body. Its wonders lie in the air we breathe and the food we eat. There is chemistry everywhere. Let us find out some of the things related to this subject that often go unnoticed.

List of Examples of Applications of Chemistry in Everyday life

1. the composition of the human body.

Our body is made of millions of compounds. We don’t even know them all. All these chemical compounds are a combination of a few constituent elements such as carbon, hydrogen, nitrogen, oxygen, calcium, phosphorus, sulfur, etc.

The variation in combination creates different formulas. These compounds get set to form something very important. Remember each type of compound we find in our body has a purpose. Whether it is constructing the cell membrane or the formation of hemoglobin, we find chemistry in every micrometer of the human body.

2. Emotional Chemistry

No, this is not about chemistry that makes you emotional. There are biochemical compounds that control your mood. Take this Chemistry in everyday life notes. The emotions a human feels depend on the hormones his brain releases. Every human makes happy and sad hormones that maintain balance.

In fact, your body shows stress due to the accumulation of certain compounds called cortisols. You feel happy when your body releases endorphins, dopamine, serotonin, and oxytocin. These are biochemical messengers that control your emotions and mood.

3. The Food You Eat

The bread you eat is fluffier and softer than before. Cereals, fruits, fish, chicken, and other staple food you eat need proper condiments and ingredients. All these ingredients are prepared following various chemical processes. This is one of the best facts that prove how Ch emistry is used in daily life.

Moreover, the food we eat is all based on the plants making food from photosynthesis. It is the base of all ecosystems. They are the producers that know how to harness solar energy to make food with carbon dioxide and water. The rest of the food chain depends on it.

What do you do when you enter your home after winning a game on the field? You wash your hands and legs with soap. Doctors recommend using sanitizers before we eat outside. Well, there is chemistry in hygiene.

The formation of soap takes place through the process of saponification. The soap molecules form micelles in water that can grab the dirt and loosen it from the surface. So, when you wash your hands or clothes, the same thing happens. Dirt can be easily cleaned due to such a chemical reaction.

When you apply sanitizer, the alcohol present in it will dissolve all the germs and microbes present in your hands. It vigorously reacts with the cellular components and destroys microbial life without leaving a trace. Your hands become clean.

5. Shedding Tears when with Onions

You might have seen people crying while cutting onions. No, they don’t feel sorry for the onions but rather experience a chemical reaction that makes their eyes watery.

There is a wonderful chemistry mystery waiting to unravel. When you slice an onion, sulphenic acid is formed from the amino acid sulphoxide compounds present in it. This acid produces a volatile gas called propanediol s-oxide. It causes our eyes to shed tears by stimulating the tear glands.

6. Baking Chemistry

How do you like your bread? Fluffy and soft? Yes! When you add baking soda to the dough, it makes the baking process easier and the bread as soft as cushions. Baking soda is nothing but a salt named sodium bicarbonate (NaHCO 3 ).

This salt breaks down to release carbon dioxide and causes the food to rise. This process is called chemical leavening. It is also used in making idlis, dosas, dhokla, etc.

7. Preservation of Food

You might have heard the saying the older the pickle the better it tastes. Have you ever wondered why some foods do not need any preservation techniques? For instance, original honey is self-preservative. You will be surprised to know that the oldest sample of honey found is 3000 years old in a tomb in Egypt. It was still edible and did not cause any harm.

This is one of the best science in everyday life examples. Pickles and honey do not need preservation as they have natural chemical compounds that do not let microbes grow. We also use chemical preservatives in packaged food to increase its shelf life.

Well, Chemistry is not always helpful. For instance, industries suffer huge losses all the time due to rusting. It is a chemical reaction that eats iron. Rust is a brown unusable substance formed on iron instruments and infrastructure when iron reacts with oxygen in presence of water vapor.

The prevention of rusting is also a brilliant solution developed using chemical science. We use antirust paint to cover the iron parts and to stop rust from progressing. We also use certain alloys that do not form rust.

You can now easily make a Chemistry in everyday life chart and display it to the class!

Importance of Chemistry in Everyday Life

From the above examples, you can now easily write down the science in everyday life essays. We have just touched the tip whereas the iceberg remains under the water. The contribution of chemistry to our lives is undeniable. If you observe carefully, you will find more examples around you.
