Gadoleic acid (20:1 n−11) is an unsaturated fatty acid. It is a prominent component of some fish oils including cod liver oil.^[2] It is one of a number of eicosenoic acids. Its name is derived from a combination of the genus for cod (Gadus) and the Latin word oleum (oil), which itself is derived from the Ancient Greek ἔλαιον (elaion) meaning olive oil.
