Chemical Information
FooDB Name(cis)-crotonaldehyde
Description(e)-2-butenal, also known as (cis)-crotonaldehyde or (E)-crotonaldehyde (iupac), 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 (e)-2-butenal is soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). (e)-2-butenal is a flower tasting compound found in fruits, garden tomato, and potato, which makes (e)-2-butenal a potential biomarker for the consumption of these food products (e)-2-butenal can be found primarily in feces and saliva.
