Metabolite Identification
Common Nametrans-2-pentenal
DescriptionTrans-2-pentenal, also known as 3-ethyl-2-propenal or 3-ethylacrolein, is a member of the class of compounds known as enals. Enals are an alpha,beta-unsaturated aldehyde of general formula RC=C-CH=O in which the aldehydic C=O function is conjugated to a C=C triple bond at the alpha,beta position. Trans-2-pentenal is soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Trans-2-pentenal can be found in a number of food items such as fruits, swiss chard, giant butterbur, and pear, which makes trans-2-pentenal a potential biomarker for the consumption of these food products.
