The word ‘Protein’ is derived from the Greek word ‘protos’ meaning "first".
Protein is the basic chemical unit of living organisms and is essential for nutrition, growth and repair.
Protein makes up the major structure of all living cells. The body’s primary building block for muscle, bone, skin, hair, and many other tissues is protein.
Protein constitutes about 15% of the body weight.
Protein contains nitrogen and sulphur in addition to carbon, hydrogen and oxygen.
Amino acids are small units that combine to form a protein molecule hence the amino acids are the building blocks of protein.
The nutritive value of protein-rich foods depends upon the total constituent of amino acids.
Simply put, protein is an important constituent of all the tissues and cells of our body, primarily found in muscle and other vital body fluids like blood.
It is vital to any organism.
Protein balance both within the body & in the diet is essential for life.
