DL-Tryptophan is an amino acid precursor of serotonin and melatonin. It is a dietary supplement for use as an antidepressant, anxiolytic, and sleep aid. DL-tryptophan also can be used as feed nutrition enhancer, antioxidants.
ChEBI: An alpha-amino acid that is alanine bearing an indol-3-yl substituent at position 3.
Tryptophan is the precursor for 5-hydroxy-tryptamin and an essential α-amino acid. DL-Tryptophan exists as a zwitterion during crystallization.
DL-Tryptophan binding to bovine serum albumin is employed for its affinity based chromatographic purification. Supplementation of tryptophan in diets of rat induce bladder tumor.
