Metabolite Identification
Common NameDocosenic acid
DescriptionDocosenic acid, also known as docosenate, is a member of the class of compounds known as very long-chain fatty acids. Very long-chain fatty acids are fatty acids with an aliphatic tail that contains at least 22 carbon atoms. Docosenic acid is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Docosenic acid can be found in peanut, which makes docosenic acid a potential biomarker for the consumption of this food product.
