The biological value of food proteins.

Proteins are essential to the growth and repair, good functioning and structure of all living cells. Hormones like insulin control blood sugar levels; enzymes such as amylase, lipase, protease are critical for the digestion of food; antibodies help us fight infections; muscle proteins allow contraction, etc.

Proteins in our body are constantly being built and removed. After we eat, proteins are destroyed by the digestion of amino acids. The amino acids are then absorbed and used to convert other proteins in the body. Adequate protein and energy intake on a daily basis will keep your cycle going.
