Metabolite Identification
Common Name2-Octenal
Description2-Octenal 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. 2-Octenal is a fatty and green tasting compound. 2-Octenal has been detected, but not quantified in, a few different foods, such as asparagus (Asparagus officinalis), cabbages (Brassica oleracea var. capitata), and cauliflowers (Brassica oleracea var. botrytis). This could make 2-octenal a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2-Octenal.
