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.
General description
Tryptophan is the precursor for 5-hydroxy-tryptamin and an essential α-amino acid. DL-Tryptophan exists as a zwitterion during crystallization.
Other Notes
Amino acid precursor of serotonin and melatonin
Preparation Note
Prepared from L-tryptophan produced by fermentation
