Metabolite Identification
Common Name2-Nonanone
Description2-Nonanone, also known as beta-nonanone or N-C7H15COCH3, belongs to the class of organic compounds known as ketones. These are organic compounds in which a carbonyl group is bonded to two carbon atoms R2C=O (neither R may be a hydrogen atom). Ketones that have one or more alpha-hydrogen atoms undergo keto-enol tautomerization, the tautomer being an enol. Thus, 2-nonanone is considered to be an oxygenated hydrocarbon. 2-Nonanone exists in all living species, ranging from bacteria to plants to humans. 2-Nonanone is a sweet, earthy, and fishy tasting compound. 2-Nonanone is found, on average, in the highest concentration within a few different foods, such as corns (Zea mays), gingers (Zingiber officinale), and cloves (Syzygium aromaticum) and in a lower concentration in beer. 2-Nonanone has also been detected, but not quantified in, several different foods, such as asparagus (Asparagus officinalis), garden tomatoes (Solanum lycopersicum), anatidaes (Anatidae), alcoholic beverages, and fruits. This could make 2-nonanone a potential biomarker for the consumption of these foods. 2-Nonanone 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. 2-Nonanone, with regard to humans, has been found to be associated with several diseases such as ulcerative colitis, crohn's disease, and nonalcoholic fatty liver disease; 2-nonanone has also been linked to the inborn metabolic disorder celiac disease. Based on a literature review a significant number of articles have been published on 2-Nonanone.
