AdipoGen 5-Hydroxy-L-tryptophan (5 g)

Chemical. CAS: 4350-09-8. Formula: C11H12N2O3. MW: 220.22. 5-hydroxy-L-Tryptophan (5-HTP), also known as oxitriptan, is a naturally occurring amino acid and chemical precursor as well as a metabolic intermediate in the biosynthesis of the neurotransmitter serotonin. It is used as a dietary supplement for use as an antidepressant, appetite suppressant, and sleep aid. It is also used as L-aromatic amino acid decarboxylase substrate. When injected systemically in animals, 5-HTP is converted to serotonin and has both peripheral and central nervous system effects. 5-HTP can also be synthesized by gut microbiota and acts as an activator of the aryl hydrocarbon receptor.
