Metabolite Identification
Common Name3-Methyl-1,2-cyclopentanedione
Description3-Methyl-1,2-cyclopentanedione, also known as benzil-related compound, 45 or corylone, belongs to the class of organic compounds known as cyclic ketones. These are organic compounds containing a ketone that is conjugated to a cyclic moiety. 3-Methyl-1,2-cyclopentanedione is an extremely weak basic (essentially neutral) compound (based on its pKa). 3-Methyl-1,2-cyclopentanedione is a sweet, caramel, and coffee tasting compound. Outside of the human body, 3-Methyl-1,2-cyclopentanedione has been detected, but not quantified in, cereals and cereal products and coffee and coffee products. This could make 3-methyl-1,2-cyclopentanedione a potential biomarker for the consumption of these foods.
