Protein


After water, proteins are the most abundant compounds in the body. Proteins are part of all living cells. One fifth of adult body weight is protein. Nearly half the amount of protein is present in the muscle, one fifth is present in the bone, one-tenth on the skin, the rest is spread in Protein is also called egg-egg white odor as it is first found in egg white.

Protein is a chemical compound built by amino acids and is built by elements of C, H, O, N, S, P. Based on the chemical arrangement of proteins Simple protein, which does not bind to other compounds The combined protein, which binds to other substances such as the glycoprotein , Chromoproteins, etc.

Derivatives of proteins such as gelatin, peptone, etc. During digestion, proteins are broken down into amino acids. The human body needs 8-10 kinds of amino acids (essential) derived from food and is absolutely necessary by the body for maintenance and growth but the body can not make itself. But there are also amino acids (non-essential) needed by the body but our body can still make itself.

The type and proportion of amino acids in food greatly determine the quality of the protein. Proteins containing all essential amino acids in proportions capable of providing optimal growth are called complete proteins or good quality proteins or high biological protein. Incomplete proteins are called low-grade proteins because they do not possess or have a limited number of essential amino acids. Most vegetable proteins are low-quality proteins except soybeans.
