MELATONIN SYNTHESIS AND METABOLISM Melatonin Synthesis Melatonin (N-acetyl-5-methoxytryptamine) is synthesized within the pinealocytes from tryptophan, mostly occurring during the dark phase of the day, when there is a major increase in the activity of serotonin-N-acetyltransferase (arylalkylamine N-acetyltransferase, AA-NAT), responsible for the transformation of 5-hydroxytryptamine (5HT, serotonin) to N-acetylserotonin (NAS) (Figure 1)
