Metabolite Identification
Common Name(E)-2-octenal
Description(E)-2-octenal, also known as 2-octen-1-al or (2E)-oct-2-enal, belongs to the class of organic compounds known as medium-chain aldehydes. These are an aldehyde with a chain length containing between 6 and 12 carbon atoms (E)-2-octenal is a green tasting compound (E)-2-octenal is found, on average, in the highest concentration within black walnuts (Juglans nigra) (E)-2-octenal has also been detected, but not quantified in, burdocks (Arctium lappa). This could make (e)-2-octenal a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on (E)-2-octenal.
