Metabolite Identification
Common Name2-Acetyloxazole
Description2-Acetyloxazole 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-Acetyloxazole has been detected, but not quantified in, a few different foods, such as cocoa and cocoa products, cocoa beans (Theobroma cacao), and nuts. This could make 2-acetyloxazole a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2-Acetyloxazole.
