Metabolite Identification

Common Name

4-Acetyl-3-methylpyridine

Description

4-Acetyl-3-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-3-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-3-methylpyridine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 4-Acetyl-3-methylpyridine.
