Docosatrienoic acid, also known as docosatrienoate, belongs to the class of organic compounds known as very long-chain fatty acids. These are fatty acids with an aliphatic tail that contains at least 22 carbon atoms. Docosatrienoic acid is a very hydrophobic molecule, is practically insoluble (in water), and is relatively neutral. Application of docosatrienoic acid was shown to dose-dependently decrease the peak K+ current amplitude and accelerate the potassium activation and inactivation kinetics at all membrane potentials.
