Chemical Information
FooDB Name7-Octadecenoic acid
Description7-octadecenoic acid is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Thus, 7-octadecenoic acid is considered to be a fatty acid lipid molecule. 7-octadecenoic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). 7-octadecenoic acid can be found in dill, which makes 7-octadecenoic acid a potential biomarker for the consumption of this food product.
