Metabolite Identification
Common Name2-oxo-6-methylthiohexanoate
Description2-oxo-6-methylthiohexanoate, also known as 6-(methylthio)-2-oxohexanoic acid, belongs to medium-chain keto acids and derivatives class of compounds. Those are keto acids with a 6 to 12 carbon atoms long side chain. 2-oxo-6-methylthiohexanoate is practically insoluble (in water) and a weakly acidic compound (based on its pKa). 2-oxo-6-methylthiohexanoate can be found in a number of food items such as soursop, nance, turmeric, and strawberry guava, which makes 2-oxo-6-methylthiohexanoate a potential biomarker for the consumption of these food products.
