Metabolite Identification
Common Name2-Acetylpyrrole
Description2-Acetylpyrrole, also known as fema 3202 or pyrrole, 2-acetyl, belongs to the class of organic compounds known as aryl alkyl ketones. These are ketones have the generic structure RC(=O)R', where R = aryl group and R'=alkyl group. 2-Acetylpyrrole is an extremely weak basic (essentially neutral) compound (based on its pKa). 2-Acetylpyrrole is a bread, nut, and walnut tasting compound. Outside of the human body, 2-Acetylpyrrole has been detected, but not quantified in, tea. This could make 2-acetylpyrrole a potential biomarker for the consumption of these foods. A pyrrole carrying an acetyl substituent at the 2-position.
