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.
Safety Profile
Experimental reproductive effects. Questionable carcinogen with experimental carcinogenic data. When heated to decomposition it emits toxic fumes of NOx.
