Erucic acid also known as cis-13-Docosenoic acid is a monounsaturated omega-9 fatty acid. It occurs at high concentrations mainly in the seeds of species of the Brassicaceae (e.g. rape seed or mustard seed, and seeds from vegetable crops such as kales, cabbages and turnips).
High-erucic acid oils are used either directly as lubricants (e.g. in the manufacture of rubber additives) or in formulations. They are used as spinning lubricants in the textile, steel, and shipping industries; as cutting, metal-forming, rolling, fabricating, and drilling oils; and as marine lubes. Erucic acid can also be oxidatively cleaved to brassylic acid for use in the production of polyesters. The oxidative cleavage of erucic acid can be performed via ozonolysis or by reaction with hydrogen peroxide in the presence of an inorganic oxide catalyst. Erucic acid can be used to prepare useful nitrogen derivatives: behenyl amine is used in a corrosion inhibitor; disubstituted amides are effective plasticizers and erucamide is an excellent slip and antiblocking agent for plastic films.
13(Z)-Docosenoic acid is a 22-carbon monounsaturated fatty acid. It is found predominantly in canola oil. 13(Z)-Docosenoic acid is metabolized to oleic acid in vivo. Diets rich in 13(Z)-docosenoic acid were shown to cause heart lipidosis in experimental animals. The C-1 amide of docosenoic acid has been identified as one of the anandamide-related neurotransmitters associated with sleep.

ChEBI: A docosenoic acid having a cis- double bond at C-13. It is found particularly in brassicas - it is a major component of mustard and rapeseed oils and is produced by broccoli, Brussels sprouts, kale, and wallflowers.
