Metabolite Identification
Common Name2-(Methylthio)ethanol
Description2-(Methylthio)ethanol, also known as 2-methylmercaptoethanol, belongs to the class of organic compounds known as dialkylthioethers. These are organosulfur compounds containing a thioether group that is substituted by two alkyl groups. 2-(Methylthio)ethanol is a meaty and sulfurous tasting compound. 2-(Methylthio)ethanol has been detected, but not quantified in, mung beans (Vigna radiata) and soy beans (Glycine max). This could make 2-(methylthio)ethanol a potential biomarker for the consumption of these foods. 2-(Methylthio)ethanol 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 2-(Methylthio)ethanol.
