Cetoleic acid is a long-chain, monounsaturated fatty acid in the omega-11 fatty acid group . The mono-acid with a cis - double bond is an isomer of erucic acid (13 Z ) -Docosensäure. The trans form is (11 E ) -11-docosenoic acid or catelaidic acid .
In the wax esters in jojoba oil is to contain 15-20%, in Avellanaöl from the Chilean hazelnut ( Gevuina avellana ) about 9-10% are included. In various vegetable oils it comes esterified as triacylglycerol in small amounts before, as in fish oils , Tran and cod liver oil .
