Common NameHexenoic acid
DescriptionHexenoic acid, also known as a,b-hexenoate or alpha,beta-hexenoic acid, is a member of the class of compounds known as medium-chain fatty acids. Medium-chain fatty acids are fatty acids with an aliphatic tail that contains between 4 and 12 carbon atoms. Hexenoic acid is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Hexenoic acid can be found in tea, which makes hexenoic acid a potential biomarker for the consumption of this food product.
