Wide Range of Aminos Are Needed

June 2005

More than 50,000 proteins help make up the human body and all those proteins are made up of different combinations of amino acids. Twenty-two amino acids are needed to build the various proteins used in the growth, repair and maintenance of body tissues. The body itself can make 13 of those amino acids, while the other nine (called essential amino acids) must come from the diet. The essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Nonessential aminos include alanine, arginine, asparagines, aspartic acid, carnitine, glutamic acid, glutamine, glycine, proline, serine, taurine, and tyrosine.
