| Common Name | 2-Decanone |
|---|
| Description | 2-Decanone, also known as N-C8H17COCH3 or decan-2-one, 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-decanone is considered to be an oxygenated hydrocarbon lipid molecule. A methyl ketone that is decane in which the methylene hydrogens at position 2 are replaced by an oxo group. 2-Decanone is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. 2-Decanone is found, on average, in the highest concentration within kohlrabis. This could make 2-decanone a potential biomarker for the consumption of these foods. 2-Decanone, with regard to humans, has been found to be associated with several diseases such as nonalcoholic fatty liver disease, ulcerative colitis, and crohn's disease; 2-decanone has also been linked to the inborn metabolic disorder celiac disease. |
