Metabolite Identification
Common Name4-Methyl-3-penten-2-one, 9CI
Description4-Methyl-3-penten-2-one, 9CI, also known as isopropylidene acetone or (CH3)2C=chc(=o)CH3, belongs to the class of organic compounds known as enones. Enones are compounds containing the enone functional group, with the structure RC(=O)CR'. Thus, 4-methyl-3-penten-2-one, 9CI is considered to be an oxygenated hydrocarbon lipid molecule. 4-Methyl-3-penten-2-one, 9CI is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 4-Methyl-3-penten-2-one, 9CI is a sweet, acrylic, and chemical tasting compound. Outside of the human body, 4-Methyl-3-penten-2-one, 9CI has been detected, but not quantified in, several different foods, such as orange bell peppers, pepper (c. frutescens), herbs and spices, yellow bell peppers, and green bell peppers. This could make 4-methyl-3-penten-2-one, 9CI a potential biomarker for the consumption of these foods. 4-Methyl-3-penten-2-one, 9CI is a potentially toxic compound. 4-Methyl-3-penten-2-one, 9CI, with regard to humans, has been linked to the inborn metabolic disorder celiac disease.
