Metabolite Identification
Common Name3-Hydroxymelatonin
Description3-Hydroxymelatonin is a metabolite of melatonin. Melatonin Listen/ˌmɛləˈtoʊnɪn/, also known chemically as N-acetyl-5-methoxytryptamine, is a naturally occurring compound found in animals, plants, and microbes. In animals, circulating levels of the hormone melatonin vary in a daily cycle, thereby allowing the entrainment of the circadian rhythms of several biological functions. (Wikipedia)
