Beschreibung

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
