Proteins are extremely complicated molecules of living things. They are: Nitrogenous compound made up of a variable number of amino acids. The human body probably contains at least 10,000 different kinds of proteins .The name protein is derived from the Greek word "proteins" meaning of 'prime importance'.
Proteins are present in all living organisms and without proteins life would not be possible. They are present in muscles, skin, hair and other tissue that make up the bulk of the body non-bony structure .All proteins contain the element of carbon, hydrogen, oxygen, nitrogen and sulpher. They may also contain phosphorus and traces of other elements like iron, copper, iodine, manganese and zinc.
Protein takes an essential part in the formation of protoplasm, which is essence of all forms of life. Enzymes, which are biological catalysts, are protein in nature. Without them life is not possible. Many proteins have specialized function. Hemoglobin acts as a carrier of oxygen. Some proteins act as hormones which have regularity function for example; insulin, thyroxin etc. Nucleoproteins, which are complexes of proteins with nucleic acids, serve as carrier of heredity from one generation to the other generation.

The amount of protein each person needs is never the same, and also varies per individual.
Age, one's general state of health, and nutrition alter the body's need for protein. And in a stable dietary environment, despite how much is ingested, the body regulates protein to keep its internal mechanisms constant.Unlike fat and carbohydrates, protein cannot be stored. Excess protein is burned for energy or stored as fat, and its nitrogen is passed as urine.

An approximate measure of the minimum amount of protein an individual needs exists, and this is the basis of the RDA (recommended daily allowance) recommendations. The recommended daily figure is 0.8 grams of protein per every kilogram of ideal (lean) body weight -- or 56 grams per day for a 77-gram (170-pound) man and 46 grams per day for a 58 kilogram (128-pound) woman.

But there are times when extra protein is needed by the body: pregnancy, lactation, major trauma (like surgery), during fever and pronounced sweating, and when a very low-calorie diet is ingested.

The word protein has been derived from a Greek word 'Protos' which means the first element. As the name suggests that it is the first element it means that it certainly is an important element.

The reason for proteins being essential for our body or human body is that proteins are made up of amino acids. In a human body there are certain amino acids which the body can make itself however there are certain such amino acids which the body cannot make. so in order to complete the ratio in the body proteins are used so that wherever the body lacks in making amino acids, it can be done by proteins which contain all the amino acids.

When the body has adequate proteins it helps in making you feel lot better and energizes you and you feel fresh, however lack of body to make proteins would lead to adverse effects.

For that matter proteins should be taken in your daily diet as it is found in meat, eggs, nuts, cheese, dairy products, soy and also in a lot of vegetables.
