Metabolite Identification
Common NameEthyl 3-(methylthio)propanoate
DescriptionEthyl 3-(methylthio)propanoate, also known as ethyl methyl mercaptopropionate, belongs to the class of organic compounds known as carboxylic acid esters. These are carboxylic acid derivatives in which the carbon atom from the carbonyl group is attached to an alkyl or an aryl moiety through an oxygen atom (forming an ester group). Ethyl 3-(methylthio)propanoate is a fruity, metallic, and pineapple tasting compound. Ethyl 3-(methylthio)propanoate is found, on average, in the highest concentration within pineapples (Ananas comosus). Ethyl 3-(methylthio)propanoate has also been detected, but not quantified in, several different foods, such as alcoholic beverages, asian pears (Pyrus pyrifolia), fruits, and milk and milk products. This could make ethyl 3-(methylthio)propanoate a potential biomarker for the consumption of these foods. Ethyl 3-(methylthio)propanoate 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 Ethyl 3-(methylthio)propanoate.
