Chemical Information
FooDB Name5-Hydroxy-L-tryptophan
Description5-Hydroxy-L-tryptophan, also known as 5-HTP or levothym, belongs to the class of organic compounds known as serotonins. Serotonins are compounds containing a serotonin moiety, which consists of an indole that bears an aminoethyl a position 2 and a hydroxyl group at position 5. 5-Hydroxy-L-tryptophan exists in all living organisms, ranging from bacteria to humans. 5-Hydroxy-L-tryptophan has been detected, but not quantified in, several different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), domestic pigs (Sus scrofa domestica), french plantains (Musa X paradisiaca), and milk (cow). This could make 5-hydroxy-L-tryptophan a potential biomarker for the consumption of these foods. 5-Hydroxy-L-tryptophan, with regard to humans, has been found to be associated with several diseases such as ulcerative colitis, colorectal cancer, and crohn's disease; 5-hydroxy-L-tryptophan has also been linked to the inborn metabolic disorder aromatic l-amino acid decarboxylase deficiency. Based on a literature review a significant number of articles have been published on 5-Hydroxy-L-tryptophan.
