Metabolite Identification
Common Name2-Dodecanone
Description2-Dodecanone, also known as dodecan-2-one or dodecanone-(2), 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-dodecanone is considered to be an oxygenated hydrocarbon lipid molecule. 2-Dodecanone is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 2-Dodecanone is a citrus, floral, and fruity tasting compound. Outside of the human body, 2-dodecanone has been detected, but not quantified in, several different foods, such as alcoholic beverages, fats and oils, garden tomato, and herbs and spices. This could make 2-dodecanone a potential biomarker for the consumption of these foods. 2-Dodecanone has been found to be associated with several diseases such as crohn's disease and ulcerative colitis; also 2-dodecanone has been linked to the inborn metabolic disorders including celiac disease.
