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.[1]

Application

D-Tryptophan has been used to study its efficacy on dispersing biofilm in dental unit waterlines (DUWLs) in vitro.[2]
D-Tryptophan can be used for Human embryonic kidney cell (HEK-293, ATCC: CRL-1573) culture.[3]The product is a sweetener used to study the release of incretins from enteroendocrine cells triggered by sugar but not by sweeteners.[4]

Biochem/physiol Actions

Low level of D-tryptophan is capable of preventing the growth of an L-tryptophan-requiring mutant of the E. coli.[5]

Other Notes

Unnatural isomer of tryptophan.
