Metabolite Identification
Common Name5-Methyl-2-phenyl-2-hexenal
Description5-Methyl-2-phenyl-2-hexenal belongs to the class of organic compounds known as phenylacetaldehydes. Phenylacetaldehydes are compounds containing a phenylacetaldehyde moiety, which consists of a phenyl group substituted at the second position by an acetalydehyde. 5-Methyl-2-phenyl-2-hexenal is a sweet, aldehydic, and bitter tasting compound. 5-Methyl-2-phenyl-2-hexenal 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 5-methyl-2-phenyl-2-hexenal a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 5-Methyl-2-phenyl-2-hexenal.
