Metabolite Identification
Common Name3-Methyl-2-pentanone
Description3-Methyl-2-pentanone 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, 3-methyl-2-pentanone is considered to be an oxygenated hydrocarbon lipid molecule. 3-Methyl-2-pentanone is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
