Amino Acids

Amino acids are carboxylic acids containing amino groups. Amino acids are the building blocks of protein for animal nutrition. Proteins in living things are made up of 20 basic amino acids.

Amino acids in human body through metabolism can play the following roles: (1) synthesis of tissue protein; (2) into acids, hormones, antibodies, creatine and other ammonia containing substances; (3) to carbohydrates and fat; (4) oxidation into carbon dioxide and water and urea, produce energy.

Alanine for the synthesis of Alitame, intermediate amino acid Serine, nonessential amino acid Arginine
