包装 1 g in poly bottle 100, 250 mg in poly bottle Biochem/physiol Actions Immediate precursor of melatonin. It is formed from serotonin and acetyl-CoA in a reaction catalyzed by serotonin N-acetyl transferase, the rate-limiting enzyme in melatonin biosynthesis. This indoleamine is a weak agonist at melatonin receptors, and has moderate effects on G-protein stimulation and inhibition of cAMP accumulation. |
