5 Importance of Chemistry in daily life
There are many chemical substances which play important role in our daily life such as medicines, drugs, food preservatives, soaps and detergents etc. Let’s discuss few of them which are highly useful for human beings. Let’s start with drugs which are externally administered substances. They modify the chemical reactions which occur in the living body. They are specific molecules which show a particular pharmacological or physiological action on an organism. They are medicines with complete formulation of the means of administering the drug to a patient. For example analgesics or anti-inflammatory agent are drugs which are used for the reduction of pain. Some common examples of analgesics are aspirin (C9H8O4), paracetamol (C8H9NO2) and ibuprofen (C13H18O2).
All these molecules contain the aromatic ring with 6 carbon atoms that is benzene. We know that benzene is one of the simplest aromatic compounds. Now days, the modern pharmaceutical industry is completely bases on herbs and other traditional ways. For example willow herb can be extracted from seeds and leaves of the willow tree. It is generally used for the treatment of headaches and as pain relaxation in childbirth. The ingestion of it hydrolyses it and gives salicylic acid from the precursor molecules. The German chemist Hoffmann prepared aspirin by the chemical modifications of salicylic acid in 1890. Similarly the oil of winter green also extracted from plants.
The chemical name of oil of wintergreen is methyl ester of salicylic acid. It also has similar medicinal effects. Aspirin is another important drug which is sparingly soluble in water. It is prepared by the neutralisation the carboxylic acid in the presence of bases such as NaOH and forms soluble sodium salt of the acid. Other useful chemicals are food additives, packing materials, food preservatives etc. Food additives provide colour, flavour and sweetness to the food materials. Some of the food additives are harmful for human health such as some of these chemicals show carcinogenic effect. The coloured food materials are attractive and easy the consumer’s perception. We can observe the composition of food colouring with the help of paper or thin layer chromatography. The use of flavours in food stuff makes the food tastier and less bland. Preservatives are generally used to preserve food for long time. Microorganisms such as bacteria or fungi can easily oxidise and causes rancidity of food. The addition of preservative avoids the growth of these microorganisms.
The use of antioxidants prevents the oxidation process of oils or fats in the presence of oxygen or air. Similarly addition of sweeteners counters the bitterness of food and adds special taste to the food. The addition of emulsifiers and stabilisers keeps all ingredients of mixture together and also protect the separation of fatty components from water based components. Processed foods such as soft drinks, topping powders, mayonnaise, cakes, biscuits, extruded snacks, peanut butter, chocolate coatings, chewing gum, margarine, breakfast cereals, coffee whiteners, ice-cream, mousses, dried potato and bread contain emulsifiers. Use of emulsifier provides a better texture and appearance to food such as salad dressings, paints and ice creams.

Question:I have an homework about 5 importance of chemistry in our daily life, but i cant find the answer.
So Help Please x
Answers:You need homework in English. I'm sure the homework assignment is only for you to realize that chemistry is everywhere and without we would not be a civilized and highly technical world.
Chemistry explains how food changes as you cook it, how it rots, how to preserve food, how your body uses the food you eat, and how ingredients interact to make food.
Part of the importance of chemistry is it explains how cleaning works. You use chemistry to help decide what cleaner is best for dishes, laundry, yourself, and your home. You use chemistry when you use bleaches and disinfectants and even ordinary soap and water. How do they work? That's chemistry!
You need to understand basic chemistry so you can understand how vitamins, supplements, and drugs can help or harm you. Part of the importance of chemistry lies in developing and testing new medical treatments and medicines.
* Environmental Issues
Chemistry is at the heart of environmental issues. What makes one chemical a nutrient and another chemical a pollutant? How can you clean up the environment? What processes can produce the things you 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 your body is made of chemicals. Chemical reactions occur when you 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.
Question:can ne 1 tell me about this?
Answers:You can not image any thing without use of chemistry.Say for medicines, petrochemicals and fertilisers ( Made up of crude oil and natural gas or any other C-H compound), Inorganic Chemistry is used for metals and its derivatives a long list of such items.Organic Chemistry just we cannot image. and the derivatives from this like soap, cosmetics,medicines,furniture, switchs,power, cells, circuits,cables,insulation,pipes, -------
Question:I need to know how these techniques have become a part of our daily life, I'm guessing water purification is one of them and i need to know both the advantages and disadvantages. I also need to know how these problems can be solved by myself, as an individual....Thank You..
Answers:There is so much on the web about this that it is easier to read for yourself and pick out what you want.
Suggest you start with http://en.wikipedia.org/wiki/Separation_process
Question:people's daily life is around water. Mostly, the first thing we did in the morning is to wash our face, which needs water. say some examples about water in our daily life to show why it is so important for our daily life
Answers:Well basically your body is made up of 85% water. This gets depleted when you urinate or sweat, if you don't refill this quota of water you will suffer from whats called Dehydration. Also water acts as a cleanser which is a property that only it posses.
