Metabolite Identification
Common Name2-Methyl-5-(methylthio)furan
Description2-Methyl-5-(methylthio)furan, also known as fema 3366 or methyl 5-methylfuryl sulfide, belongs to the class of organic compounds known as aryl thioethers. These are organosulfur compounds containing a thioether group that is substituted by an aryl group. 2-Methyl-5-(methylthio)furan is a coffee, garlic, and horseradish tasting compound. 2-Methyl-5-(methylthio)furan has been detected, but not quantified in, a few different foods, such as arabica coffees (Coffea arabica), coffee and coffee products, and robusta coffees (Coffea canephora). This could make 2-methyl-5-(methylthio)furan a potential biomarker for the consumption of these foods. 2-Methyl-5-(methylthio)furan 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-Methyl-5-(methylthio)furan.
