L-Tryptophan 是一种必需氨基酸，是褪黑素、血清素和维生素B3的前体。

L-Tryptophan, an essential amino acid, is necessary for normal growth in infants and for nitrogen balance in adults. It is a precursor of SEROTONIN (hence its use as an antidepressant and sleep aid) and of INDOLE ALKALOIDS in plants. It can be a precursor to NIACIN, although inefficiently in mammals.
