Eicosadienoic acid

Class

Small Molecule

Description

Dihomo-linoleate (20:2n6) 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. Dihomo-linoleate (20:2n6) is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Dihomo-linoleate (20:2n6) can be found in black walnut, which makes dihomo-linoleate (20:2n6) a potential biomarker for the consumption of this food product. Dihomo-linoleate (20:2n6) can be found primarily in blood and saliva.
