Common Name | 3-Hydroxymelatonin |
---|
Description | 3-Hydroxymelatonin belongs to the class of organic compounds known as indolines. Indolines are compounds containing an indole moiety, which consists of pyrrolidine ring fused to benzene to form 2,3-dihydroindole. 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. 3-Hydroxymelatonin is a strong basic compound (based on its pKa). 3-Hydroxymelatonin is a metabolite of melatonin. |
