Metabolite Identification
Common Name(Methylthio)acetone
Description(Methylthio)acetone belongs to the class of organic compounds known as ketones. These are organic compounds in which a carbonyl group is bonded to two carbon atoms R2C=O (neither R may be a hydrogen atom). Ketones that have one or more alpha-hydrogen atoms undergo keto-enol tautomerization, the tautomer being an enol (Methylthio)acetone is a melon tasting compound (Methylthio)acetone has been detected, but not quantified in, fats and oils and pulses. This could make (methylthio)acetone a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on (Methylthio)acetone.
