Chemical Information
FooDB NameSterculic acid
DescriptionSterculic acid, also known as 2-octyl-1-cyclopropene-1-octanoic acid or 8-(2-octyl-cycloprop-1-enyl)-octansaeure, 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. Thus, sterculic acid is considered to be a fatty acid lipid molecule. Sterculic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Sterculic acid can be found in peanut and roselle, which makes sterculic acid a potential biomarker for the consumption of these food products.
