Metabolite Identification
Common Namedi-Hydroxymelatonin
Descriptiondi-Hydroxymelatonin belongs to the class of organic compounds known as n-acetyl-2-arylethylamines. N-acetyl-2-arylethylamines are compounds containing an acetamide group that is N-linked to an arylethylamine. di-Hydroxymelatonin is an extremely weak basic (essentially neutral) compound (based on its pKa). di-Hydroxymelatonin is a metabolite of melatonin. 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. Melatonin Listen/ˌmɛləˈtoʊnɪn/, also known chemically as N-acetyl-5-methoxytryptamine, is a naturally occurring compound found in animals, plants, and microbes.
