General description
Tryptophan is the precursor for 5-hydroxy-tryptamin and an essential α-amino acid. DL-Tryptophan exists as a zwitterion during crystallization.
Application
DL-Tryptophan has been used:
- as a medium supplement in Psilocybe atrobrunnea and Psilocybe serbica for the synthesis of psychotropic compounds
- as an optimal medium supplement for culturing yeast, Pichia stipitis
- for chiral separation experiments using Hewlett-Packard HP3D CE capillary electrophoresis system(HPCE)
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.
Preparation Note
Prepared from L-tryptophan produced by fermentation
Other Notes
Amino acid precursor of serotonin and melatonin
