proteinogenic amino acid
Definition : Any of the 23 alpha-amino acids that are precursors to proteins, and are incorporated into proteins during translation. The group includes the 20 amino acids encoded by the nuclear genes of eukaryotes together with selenocysteine, pyrrolysine, and N-formylmethionine. Apart from glycine, which is non-chiral, all have L configuration.
