Metabolite Identification

Common Name

4-Penten-2-one

Description

4-Penten-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, 4-penten-2-one is considered to be an oxygenated hydrocarbon. 4-Penten-2-one has been detected, but not quantified in, fruits and tamarinds (Tamarindus indica). This could make 4-penten-2-one a potential biomarker for the consumption of these foods. 4-Penten-2-one is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review very few articles have been published on 4-Penten-2-one.
