Metabolite Identification
Common Name3-Mercapto-3-methyl-1-butanol
Description3-Mercapto-3-methyl-1-butanol, also known as 3-methyl-3-sulfanyl-1-butanol, belongs to the class of organic compounds known as alkylthiols. These are organic compounds containing the thiol functional group linked to an alkyl chain. 3-Mercapto-3-methyl-1-butanol is a sweet, meat broth, and roasted tasting compound. 3-Mercapto-3-methyl-1-butanol has been detected, but not quantified in, several different foods, such as alcoholic beverages, arabica coffees (Coffea arabica), coffee and coffee products, fruits, and robusta coffees (Coffea canephora). This could make 3-mercapto-3-methyl-1-butanol a potential biomarker for the consumption of these foods. 3-Mercapto-3-methyl-1-butanol is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on 3-Mercapto-3-methyl-1-butanol.
