- are now considered semiessential because if the diet contains them
- (meat, milk, fish, poultry and legumes are good sources), the body can
- use them in place of two essential amino acids methionine and
- phenylalanine, respectively to make protein. The nonessential amino
- acids are ALANINE, ARGININE, ASPARAGINE, ASPARTIC ACID, GLUTAMIC ACID, GLUTAMINE, GLYCINE, PROLINE, SERINE and TAURINE. builds tissue in muscles ect.
