The gadoleic or (9 Z ) -Eicosensäure is a simple unsaturated fatty acid consisting of a linear chain of 20 carbon atoms with cis consists double bond. The double bond is on the ninth carbon atom from the delta end, which is why it belongs to the omega-11 fatty acids and is referred to with the lipid name 20: 1 (ω − 11). Monoenoic acid is an isomer of gondo acid , (11 Z ) -eicosenoic acid.
Occurrence
Gadoleic acid occurs as a natural fatty acid and as a component of the corresponding triglycerides in various vegetable oils , but mostly only in small quantities. It occurs in cabbage species ( Brassica ) z. B. in rapeseed and broccoli seed oil as well as mustard oil , it is also found in fish oils .
