| | DL-Tryptophan Usage And Synthesis |
| 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. | | reaction suitability | reaction type: solution phase peptide synthesis | | 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. |
