DL-Tryptophan Chemical Properties,Uses,Production
Chemical Properties
White crystals. Slightly soluble in water; stable in alkaline solution; decomposed by strong acids.Uses
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.Definition
ChEBI: An alpha-amino acid that is alanine bearing an indol-3-yl substituent at position 3.General Description
Tryptophan is the precursor for 5-hydroxy-tryptamin and an essential α-amino acid. DL-Tryptophan exists as a zwitterion during crystallization.Biochem/physiol Actions
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.Safety Profile
Experimental reproductive effects. Questionable carcinogen with experimental carcinogenic data. When heated to decomposition it emits toxic fumes of NOx.DL-Tryptophan Preparation Products And Raw materials
