Metabolite Identification
Common NameEthyl methyl sulfide
DescriptionEthyl methyl sulfide 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. Ethyl methyl sulfide is a cabbage, citrus, and coffee tasting compound. Ethyl methyl sulfide has been detected, but not quantified in, several different foods, such as evergreen blackberries (Rubus laciniatus), garden onions (Allium cepa), arabica coffees (Coffea arabica), coffee and coffee products, and green onion. This could make ethyl methyl sulfide a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Ethyl methyl sulfide.
