Metabolite Identification
Common Name6,8-Icosanedione
Description6,8-Icosanedione, also known as eicosane-6,8-dione, belongs to the class of organic compounds known as beta-diketones. These are organic compounds containing two keto groups separated by a single carbon atom. 6,8-Icosanedione has been detected, but not quantified in, fats and oils. This could make 6,8-icosanedione a potential biomarker for the consumption of these foods. 6,8-Icosanedione 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 6,8-Icosanedione.
