Metabolite Identification

Common Name

2,3-Heptanedione

Description

2,3-Heptanedione, also known as heptane-23-dione or 2,3-dioxoheptane, belongs to the class of organic compounds known as alpha-diketones. These are organic compounds containing two ketone groups on two adjacent carbon atoms. Thus, 2,3-heptanedione is considered to be an oxygenated hydrocarbon lipid molecule. 2,3-Heptanedione is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. 2,3-Heptanedione is a butter, cheese, and oily tasting compound. 2,3-Heptanedione has been detected, but not quantified, in several different foods, such as alcoholic beverages, garden tomato, mushrooms, and pulses. This could make 2,3-heptanedione a potential biomarker for the consumption of these foods.
