Metabolite Identification
Common Name2-Acetylthiophene
Description2-Acetylthiophene, also known as 2-acetothienone or thiophene,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-Acetylthiophene is a sulfury tasting compound. 2-Acetylthiophene is found, on average, in the highest concentration within kohlrabis. 2-Acetylthiophene has also been detected, but not quantified, in asparagus. This could make 2-acetylthiophene a potential biomarker for the consumption of these foods.
