DrugBank ID	DB00150
Name	Tryptophan
Groups	nutraceutical withdrawn approved
Description	An essential amino acid that is necessary for normal growth in infants and for nitrogen balance in adults. It is a precursor of indole alkaloids in plants. It is a precursor of serotonin (hence its use as an antidepressant and sleep aid). It can be a precursor to niacin, albeit inefficiently, in mammals.
Synonyms	Tryptophane (S)-alpha-Amino-beta-(3-indolyl)-propionic acid (2S)-2-amino-3-(1H-indol-3-yl)propanoic acid Triptofano L-(-)-Tryptophan L-β-3-indolylalanine (S)-Tryptophan L-(−)-tryptophan Trp W (S)-α-amino-1H-indole-3-propanoic acid L-Tryptophan Tryptophanum Tryptophan
