Docosadienoic acid is a polyunsaturated very long-chain fatty acid (VLCFA) with a 22-carbon backbone and two double bonds.
The acid exists in several isomeric forms, depending on the positions and configurations of the double bonds. These isomers play important roles in biological systems and are used in chemical synthesis.
Insoluble in water. Soluble in chloroform, hexane, ethanol.
Docosadienoic acid can be detected in modest concentrations, generally not exceeding 3%, in the seed oils of many plants, particularly Cruciferae and Ranunculaceae.
