| Common Name | 2-Pentanone |
|---|
| Description | 2-Pentanone, also known as ethyl acetone or fema 2842, 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. 2-Pentanone is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Thus, 2-pentanone is considered to be an oxygenated hydrocarbon lipid molecule. 2-Pentanone is a sweet, alcohol, and banana tasting compound. 2-Pentanone is found, on average, in the highest concentration within milk (cow). 2-Pentanone has also been detected, but not quantified, in several different foods, such as fats and oils, corns, apples, evergreen blackberries, and fruits. This could make 2-pentanone a potential biomarker for the consumption of these foods. 2-Pentanone, with regard to humans, has been found to be associated with several diseases such as ulcerative colitis, nonalcoholic fatty liver disease, and crohn's disease; 2-pentanone has also been linked to the inborn metabolic disorder celiac disease. |
