Metabolite Identification
Common Name2-Acetylpyridine
Description2-Acetylpyridine 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-Acetylpyridine is a chip, corn, and fatty tasting compound. 2-Acetylpyridine is found, on average, in the highest concentration within kohlrabis (Brassica oleracea var. gongylodes). 2-Acetylpyridine has also been detected, but not quantified in, several different foods, such as cereals and cereal products, cocoa beans (Theobroma cacao), cocoa and cocoa products, green tea, and red tea. This could make 2-acetylpyridine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2-Acetylpyridine.
