Metabolite Identification
Common Name2-Pentanone
Description2-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. Thus, 2-pentanone is considered to be an oxygenated hydrocarbon lipid molecule. 2-Pentanone exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. 2-Pentanone has been found to be associated with several diseases known as ulcerative colitis, nonalcoholic fatty liver disease, and crohn's disease; also 2-pentanone has been linked to the inborn metabolic disorders including celiac disease.
