Metabolite Identification
Common Name3-Methyl-3-buten-2-one
Description3-Methyl-3-buten-2-one belongs to the class of organic compounds known as alpha-branched alpha,beta-unsaturated ketones. These are alpha,beta-unsaturated ketones that carry a branch on the alpha carbon. They have the generic structure RC(=O)C(R')=C, R = organyl group and R'= any heteroatom. 3-Methyl-3-buten-2-one has been detected, but not quantified in, blackberries (Rubus) and evergreen blackberries (Rubus laciniatus). This could make 3-methyl-3-buten-2-one a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 3-Methyl-3-buten-2-one.
