Metabolite Identification
Common NameIsobehenic acid
DescriptionIsobehenic acid, also known as isobehenate, 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, isobehenic acid is considered to be a fatty acid lipid molecule. Isobehenic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Isobehenic acid can be found in corn, which makes isobehenic acid a potential biomarker for the consumption of this food product.
