WebAug 1, 1998 · Alanine is an important nitrogenous product of the intestinal catabolism of glutamine, glutamate, aspartate ( Windmueller 1982) and perhaps BCAA. Thus, alanine transaminase appears to function primarily for alanine synthesis in intestinal mucosa. Alanine may serve to transport nitrogen of some dietary amino acids to extraintestinal … WebAmino acids like alanine, tryptophan, serine, glycine, threonine, and cysteine can be converted to pyruvate.
