Metabolite Identification
Common Nametrans-10-Octadecenoic acid
Description10-octadecenoic acid, also known as isooleic 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, 10-octadecenoic acid is considered to be a fatty acid lipid molecule. 10-octadecenoic acid is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 10-octadecenoic acid can be found in peanut, which makes 10-octadecenoic acid a potential biomarker for the consumption of this food product.
