Metabolite Identification
Common Name2-Undecenal
Description2-Undecenal, also known as (2E)-2-undecenal or trans-2-undecenal, 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. Thus, 2-undecenal is considered to be a fatty aldehyde. 2-Undecenal is a citrus, fat, and fresh tasting compound. 2-Undecenal has been detected, but not quantified in, several different foods, such as milk and milk products, blackberries (Rubus), citrus, herbs and spices, and tortilla chip. This could make 2-undecenal a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 2-Undecenal.
