Metabolite Identification
Common NameEthyl isobutyl ketone
DescriptionEthyl isobutyl ketone 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, ethyl isobutyl ketone is considered to be an oxygenated hydrocarbon. Ethyl isobutyl ketone has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make ethyl isobutyl ketone a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Ethyl isobutyl ketone.
