Chemical Information
FooDB NameEthyl 3-(methylthio)propanoate
DescriptionEthyl 3-(methylthio)propanoate, also known as ethyl 3-methylmercaptopropionate or fema 3343, 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 an extremely weak basic (essentially neutral) compound (based on its pKa). Ethyl 3-(methylthio)propanoate is a fruity, metallic, and pineapple tasting compound. Ethyl 3-(methylthio)propanoate is found, on average, in the highest concentration in pineapples. Ethyl 3-(methylthio)propanoate has also been detected, but not quantified in, a few different foods, such as alcoholic beverages, fruits, and milk and milk products. This could make ethyl 3-(methylthio)propanoate a potential biomarker for the consumption of these foods.
