               Importance of chemistry in our daily life

Everything is made of chemicals. Many of the changes we observe in the world around we see that caused by chemical reactions. Chemistry is very important because it helps us to know the composition, structure& changes of matter. All the matters are made up of chemistry. In our every day like various chemical are being used in various from, some of those are being used as food, some of those used clanging etc.

                                              1 Element in the Human Body

Body is made up of chemical compounds, which are combinations of elements. Probably know body is mostly water,  which is hydrogen and oxygen,

                                                2. Health Care and Beauty:

The diagnostic tests carried out in laboratories, the prognostic estimations, medical prescriptions, pills, the vaccines, the antibiotics play very vital role in health monitoring, control of diseases and in alleviating the sufferings of the humanity. Right from birth control to enhancement of life expectancy- all have been made possible using the unequivocal services of Chemistry. From simple sterilization surgical instruments with antiseptic solution to Chemotherapy and Genome sequencing are all nothing but applications of Chemistry. Injecting cows, buffaloes, goat and sheep with bovinesome towropeIncreases milk-production but it is indiscriminately being used by sportspersons to un-ethically enhance performance. Aging- a chemical change can only be checked chemically. Most beauty products are produced through chemical synthesis to clean, nurture and protect skins. However their certain ingredients are hazardous to our health in the long run.

                                                  3. Industries and Transport:

From cloth mills, lather factories, petro-chemical industries and refineries to metal industries- all use numerous fuels for power generation and chemical products for processing their product and improve the equality and simultaneously produce pollution. Now-a-days chemical effluent treatment plants use chemicals to control or neutralist he hazardous impact of pollutants produced by the industries. Aviation and shipping industries generate power through power plants which burn fuels. Petrol and diesel emit out green house gases dangerous for the survival on earth which damage the ozone layer that protects us from UV rays. As a result global warming has taken place which is a destroyer of the planet earth. But again Chemistry paves the way with bio-fuels.

                                            4. Food Security and Agriculture:

The famous green revolution to increase agricultural produce so as to ensure food security was triggered by the advent of inorganic fertilizers. Since then fertilizers are extensively used by farmers to restore the fertility of soil in the fields. Pesticides are used to protect the crop during farming and preserve the grains from pests, rats and mice during storage. Genetically modified seeds which are used to enhance production and earn profits through export of food grains are agricultural applications of Bio-chemistry. Whereas refrigeration system for cold storage of vegetables and raw meat uses Poly Urethanes Foam (PUF) and the chemical properties of gases, the preservatives in packaged food products are known to have adverse impact on our body.

                                                   5. Science and Technology:

The destructive effects of Atom Bombs dropped on Hiroshima and Nagasaki? Generations in Japan have suffered the devastation and there has-been no solace. The threat of weapons of mass-destruction (WMDs) like the Nuclear, Chemical and Biological weapons looms large on the Humanity. Terrorists are using RDX and other explosives to run currents of fear down the spines across the globe. Nuclear reactors which are going to serve the future generations through power generation leave us with the problem of Nuclear Waste Management. Whereas the destructive power is generated through chains of chemical reactions, we remain assured that Chemistry has facilitated the chain of counter measures too in the form of safety suites and NBC resistant bunkers. Forensic science- the comprehensive scientific analysis of material evidence in the context of the law uses principles of chemistry to facilitate crime investigation. Tele-communications, Information Technology and Space Missions- all bank on the chemistry of semi-conductor sand nano-tubes.

                                                                6 Cooking
Chemistry explains how food changes as we cook it, how it rots, how to preserve food, how our body uses the food eats, and how ingredients interact to make food.

                                                                7 Cleaning
Part of the importance of chemistry is it explains how cleaning works. we use chemistry to help decide what cleaner is best for dishes, laundry, yourself, and your home. we use chemistry when use bleaches and disinfectants and even ordinary soap and water. How do they work? That's chemistry!

                                                               8 Medicine
it is very need to understand basic chemistry so that we can understand how vitamins, supplements, and drugs can help or harm us. Part of the importance’s of chemistry lies in developing and testing new medical treatments and medicines.

                                                         9Environmental Issues
Chemistry is at the heart of environmental issues. What makes one chemical a nutrient and another chemical a pollutant? How we can clean up the environment? What processes can produce the things our need without harming the environment? We're all chemists. We use chemicals every day and perform chemical reactions without thinking much about them. Chemistry is important because everything you do is chemistry! Even our body is made of chemicals. Chemical reactions occur when we breathe, eat, or just sit there reading. All matter is made of chemicals, so the importance of chemistry is that it's the study of everything.



Chemistry is present in every aspect of life, and here we can see a few examples. There are articles about the chemistry of everyday life, and also a few about physics, as it's also present in our daily life


You'll Be Amazed By These Examples of Chemistry in Everyday Life

Chemistry, though a mystery to many, is heavily involved in every aspect of our daily life. Our very existence depends upon it. There are numerous examples lying around- big and small, that can make us realize how vital chemistry is in everyday life. Let's take a look!
The human body contains enough carbon to provide 'lead' (which is really graphite) for about 9,000 pencils!
Chemistry is a branch of science, which deals with the study of the composition, structure, properties, reactions, and behavior of substances. Hence, chemistry is termed as the central science. It is the essence of our everyday lives and occurs in the food we eat, the air we breathe, the water we drink, everything is a result of chemical processes.

In fact, emotions like love and hatred are also driven by chemistry. For a better understanding of the chemistry that is virtually everywhere around us, we have provided day-to-day examples in two sections. Firstly, examples of chemistry within our body and secondly, examples of chemistry that exist outside our body or occur around us.
Chemistry plays a vital role in our survival, and life without chemicals can't even be imagined. They participate in the primary functions of the body, control our emotions, oversee the metabolic processes and keep diseases at bay. The oxygen that we breathe, the essential nutrients that we require, the genetic make-up of our body - the DNA and RNA - are all made up of different elements and compounds. Let us take a look at few such instances that involve chemistry, and are an integral part of our existence.
Composition of the Human Body
Roughly 96% of our body mass is made up of just 4 elements:- Oxygen, Carbon, Hydrogen and Nitrogen. The remaining 4% consists of around 60 elements that include sodium, potassium, calcium, zinc, and the list goes on.
The elements that are required in larger amounts are called macro-nutrients and the others that are needed in minute quantities, usually in parts per million or less, are called micro-nutrients. Chemically, the human body is made up of water and organic compounds- carbohydrates, proteins, lipids, and nucleic acids.
The organic processes taking place in the human body are termed as metabolism, which involves huge number of chemical reactions. The enzymes that are secreted by different organs act as biocatalysts that speed up the rate of these reactions, whereas the hormones regulate their occurrence, time, and speed.
Our well-being, smooth functioning and normal health depends on these metabolic processes. The coordination and simultaneous occurrences of these life processes in an orderly manner is the reason we are fit, healthy, and alive.
Breathing is the exchange of gases between an organism and its environment. Respiration is a chemical process, which is a reaction between glucose or sugars with oxygen, that release energy. It is the process in which inhalation of oxygen from the air causes inflation of the lungs, and then deflation occurs by exhaling carbon dioxide into the environment.
The reaction that takes place during breathing is :-
C6H12O6 + 6O2 ➜ 6CO2 + 6H2O + Energy
Water is the elixir of life on Earth. Hydrogen - a highly-combustible gas and Oxygen - a gas without which combustion is impossible, form a covalent bond with each other to create the most effective fire extinguisher, which is water. The chemical formula of water is H2O.
Yes! We drink a chemical everyday. Water is important for all the metabolic processes that occur inside our body. As Leonardo da Vinci stated "Water is the driving force of all nature."
When you feel hungry the hormone Ghrelin is secreted by the stomach that triggers hunger. It stimulates the release of the growth hormone. It plays a role in the release of Insulin and protection of the cardiovascular organs. So, the next time your stomach growls grab a bite because if you fast or skip meals, more Ghrelin is produced thus increasing your craving for food.
Gastric acid is composed of hydrochloric acid (HCl) and large quantities of potassium chloride(KCl) and sodium chloride(NaCl) that is secreted by the parietal cells lining the stomach.
This gastric acid helps convert pepsinogen to pepsin which is responsible for the denaturing of the proteins in the stomach. It also kills the micro-organisms in the food before they can make you sick. The HCl neutralizes the acid present in the foods you eat thereby maintaining your body's acidic or alkaline levels to keep you healthy.
Sometimes, crying is a natural reflex. Studies have shown that emotional tears contain more manganese, an element that affects temperament and more prolactin. Prolactin is a hormone that regulates milk production. This elimination of manganese and prolactin is thought to ease out tension building up in the body and you feel energized and rejuvenated. So, the next time you feel low and need to vent your emotions, don't hold back. Just cry! It will help you feel better.
We fall in love or are attracted to someone and have a feeling of belonging due to an increase in the secretion of -Phenylethylamine (PEA, or the "love chemical") and the hormones testosterone and estrogen which promote mating.
When we fall in love, our brain releases dopamine, norepinephrine and pheromones consistently, which evoke the pleasure center in the brain leading to side effects such as increased heart rate, insomnia, an intense feeling of excitement, elation, and focused attention.
Coffee keeps you awake due to the presence of caffeine in it. This caffeine increases dopamine levels in our bodies that stimulates the 'pleasure areas' in our brain making us feel good. It increases the adrenaline secretion in the body and speeds up activity in the brain that keeps us awake.
Perspiration is a way in which the body cools itself. Body odor mainly originates from the Apocrine glands, which are found in the armpits, ears, breasts, the genitals, and hair follicles that become active at the onset of puberty. The sweat that these glands release is slight yellow in color due to the presence of fatty acids and proteins in it. The bacteria that thrive on our skin break down the secretions of the Apocrine glands and create smelly odors.
These are some of the examples of chemistry inside our body. Let's look at some examples of chemistry in day-to-day life that take place around us.
Chemical reactions influence the stuff around us, and there are numerous instances where chemicals and chemistry helps us live a better life. The cooking of food, the clothes we wear, fertilizers that we use for crops, cement used for building our houses, the power plants that generate electricity, and many other processes depend on chemistry. The human dependence on this natural science is increasing and to understand this, here are a few examples that highlight the importance of chemistry around us.
Photosynthesis involves energy transformation and is a chemical process wherein plants, algae, and some bacteria produce their own food. It is the synthesis of glucose using carbon dioxide and water in presence of sunlight trapped by chlorophyll present in the leaves. The reaction which occurs is depicted as:
6 CO2 + 6 H2O + Light Energy ➜ C6H12O6 + 6 O2
Photosynthesis is the reverse process of respiration. They both are inter-dependent. We get an uninterrupted supply of oxygen, and plants get the carbon dioxide they need. Thus, photosynthesis plays a significant role in our day-to-day life.
There are two types of meat: red and white. Red meat contains a highly pigmented protein called myoglobin that stores oxygen in the muscle cells. More the myoglobin in the cells, the redder is the meat. However, as meat is heated, the proteins break down and shrink in size.
When the interior of the meat reaches 170° F, hemichrome (a tan colored compound) levels rise, and the myoglobin becomes metmyoglobin, which gives well-done meat its brown-gray shade. White meat contains glycogen, which has a translucent "glassy" quality when it is raw. When it's cooked, the proteins recombine, or coagulate, and the meat becomes opaque and whitish.
Apples contain an enzyme called polyphenol oxidase (PPO), also known as tyrosinase. Cutting an apple exposes its cells to the atmospheric oxygen and oxidizes the phenolic compounds present in apples. This is called the enzymatic browning that turns a cut apple brown. In addition to apples, enzymatic browning is also evident in bananas, pears, avocados and even potatoes.
When you cut an onion you break the cells that form the layers in an onion, thus releasing an enzyme Alliinase that reacts with a sulfur-containing compound known as 'prensco', which is also released while cutting. This reaction results in the formation of 1-propenyl sulfenic acid.
1-propenyl sulfenic acid is further converted to Propanethiol S-oxide, a volatile sulfur compound, by the enzyme LF-synthase (meaning Lachrymatory Factor synthesizing enzyme). This gas, known as the Lachrymatory factor (crying factor), reacts with the water in our eyes to form sulfuric acid causing a burning sensation in your eyes and indicating the tear gland to secrete tears.
Soap is formed by the reaction between an alkali and a fatty acid. This produces a molecule with one hydrophilic (water-loving) and one lipophilic (fat-loving) ends. The lipophilic ends stick to oil, grease, or dirt. These get engulfed in the soap and are washed away with a fresh stream of water, leaving a clean surface behind.
This is just a physical reaction that takes place. Soap and stain removers act as emulsifiers which allow oil and water to mix and so the oily mixtures and difficult stains on body and clothes can be removed after application of soap, stain removers, and water.
A simple hydrocarbon gas ethylene switches on the necessary genes that stimulate the secretion of the ripening enzymes which catalyze reactions to change the properties of the fruit. Ethylene channelizes the action of several other chemicals called hydrolase, amylase, kinase, and pectinase. These enzymes convert starch to sugar, alter the cell walls to make them softer, neutralize acids and cause the fruit to emit an aroma.
Fermentation is the conversion of complex substances to simpler ones under anaerobic conditions. The specific product from fermentation is driven by the type of micro-organisms acting on the substance in which the fermentation occurs. The products of fermentation are alcohols or acids and the release of carbon dioxide.
For example, wine produced from fruit juice is an alcohol as a result of fermentation by yeast, whereas beer is the result of yeast fermentation of grain. Antibiotics are obtained through fermentation by molds and some bacteria. Yogurt, cheese, and vinegar are products of bacterial fermentation. Leavened bread is obtained by yeast fermentation.
Sunscreens are a combination of organic and inorganic compounds. Inorganic chemicals, like titanium dioxide or zinc oxide, form a physical barrier that reflects or scatters UV waves. Organic components like octyl methoxycinnamate (OMC) or oxybenzone absorb UV rays and release their energy as heat. This protects our skin from sunburns and detrimental effects like cancer.
Nail paint consists of three types of ingredients - organic solvents and drying agents, thickeners and hardening agents, and coloring agents. The remover is actually an organic solvent that is used as an ingredient in nail paint which may be acetone or ethyl acetate.
So when you apply the remover you are just bringing it back to its original state. The solvent molecules get in between the chains of polymers and separate them, making it easy to wipe it off with a ball of cotton.
All materials are made up of electrical charges in the atoms of the material. There are equal quantities of electrons (negative charges) and protons (positive charges) that try to balance each other in the universe. Friction between two materials causes these charges to redistribute. The electrons from one atom are transferred to the other.
As we know, like charges repel each other and unlike charges attract each other. Whenever you touch anything that is a good conductor of electricity, the transfer of the extra electrons that have accumulated takes place, and it gives you the static shock. For example, generally in winters, you get a shock when you get out of the car or when you touch the door knob or filing cabinet.
Your body itself is a huge chemical factory wherein one or the other chemical reaction takes place every moment. Most people detest chemistry because of long reactions and difficult chemical names that we see in our books. However, taking a practical approach to understanding this science, that we come across in our everyday life, will help you appreciate it even more.
