Metabolite Identification
Common Name4-Acetyl-2-methylpyridine
Description4-Acetyl-2-methylpyridine 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. 4-Acetyl-2-methylpyridine has been detected, but not quantified in, a few different foods, such as arabica coffees (Coffea arabica), coffee and coffee products, and robusta coffees (Coffea canephora). This could make 4-acetyl-2-methylpyridine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 4-Acetyl-2-methylpyridine.
