General description

Tryptophan is one of the essential and standard amino acids present in the body. It is used by the cells to produce proteins.

Application

D-Tryptophan has been used to study its efficacy on dispersing biofilm in dental unit waterlines (DUWLs) in vitro.
D-Tryptophan can be used for Human embryonic kidney cell (HEK-293, ATCC: CRL-1573) culture.The product is a sweetener used to study the release of incretins from enteroendocrine cells triggered by sugar but not by sweeteners.

Biochem/physiol Actions

Low level of D-tryptophan is capable of preventing the growth of an L-tryptophan-requiring mutant of the E. coli.

Other Notes

Unnatural isomer of tryptophan.
