Chemical Information
FooDB Name3-(Methylthio)propanal
Description3-(Methylthio)propanal, also known as 3-methylsulfanylpropanal or 4-thiapentanal, belongs to the class of organic compounds known as alpha-hydrogen aldehydes. These are aldehydes with the general formula HC(H)(R)C(=O)H, where R is an organyl group. 3-(Methylthio)propanal is an extremely weak basic (essentially neutral) compound (based on its pKa). 3-(Methylthio)propanal is a beef, cooked potato, and creamy tasting compound. 3-(Methylthio)propanal has been detected, but not quantified in, several different foods, such as natal plums, cumins, pepper (c. frutescens), mamey sapotes, and black raspberries. This could make 3-(methylthio)propanal a potential biomarker for the consumption of these foods.
