essential amino acid
essential amino acid An amino acid that an organism is unable to synthesize in sufficient quantities. It must therefore be present in the diet. In humans the essential amino acids are arginine, histidine, lysine, threonine, methionine, isoleucine, leucine, valine, phenylalanine, and tryptophan. These are required for protein synthesis and deficiency leads to retarded growth and other symptoms. Most of the amino acids required by humans are also essential for all other multicellular animals and for most protozoans.
