Metabolite Identification
Common Name5-Hydroxy-L-tryptophan
Description5-Hydroxy-L-tryptophan, also known as 5-HTP or oxitriptan, 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 as a solid, possibly soluble (in water), and a very strong basic compound (based on its pKa) molecule. 5-Hydroxy-L-tryptophan participates in a number of enzymatic reactions, within cattle. In particular, 5-Hydroxy-L-tryptophan and 4a-hydroxytetrahydrobiopterin can be biosynthesized from L-tryptophan and tetrahydrobiopterin through its interaction with the enzyme tryptophan 5-hydroxylase 1. In addition, 5-Hydroxy-L-tryptophan can be converted into serotonin through its interaction with the enzyme aromatic-L-amino-acid decarboxylase. In cattle, 5-hydroxy-L-tryptophan is involved in the metabolic pathway called the tryptophan metabolism pathway. 5-Hydroxy-L-tryptophan is a potentially toxic compound.
