Metabolite Identification

Common Name

2,3-Hexanedione

Description

2,3-Hexanedione 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-hexanedione is considered to be an oxygenated hydrocarbon. 2,3-Hexanedione is a sweet, butter, and caramel tasting compound. 2,3-Hexanedione has been detected, but not quantified in, several different foods, such as pulses, fruits, mollusks, arabica coffees (Coffea arabica), and coffee and coffee products. This could make 2,3-hexanedione a potential biomarker for the consumption of these foods. 2,3-Hexanedione is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review very few articles have been published on 2,3-Hexanedione.
