| Common Name | Methyl methanethiosulfonate |
|---|
| Description | Methyl methanethiosulfonate, also known as MMTS, belongs to the class of organic compounds known as sulfonyls. Sulfonyls are compounds containing the sulfonyl group, with the general structure RS(=O)2R' ( R,R' must not be H). Methyl methanethiosulfonate exists in all living organisms, ranging from bacteria to humans. Methyl methanethiosulfonate is a pungent, roasted, and sulfurous tasting compound. Methyl methanethiosulfonate has been detected, but not quantified in, several different foods, such as red onion, welsh onions (Allium fistulosum), garden onions (Allium cepa), green onion, and garden onion (var.). This could make methyl methanethiosulfonate a potential biomarker for the consumption of these foods. Methyl methanethiosulfonate 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 Methyl methanethiosulfonate. |
