Docosadienoic acid is a polyunsaturated very long-chain fatty acid (VLCFA) with a 22-carbon backbone and two

double bond In chemistry, a double bond is a covalent bond between two atoms involving four bonding electrons as opposed to two in a single bond. Double bonds occur most commonly between two carbon atoms, for example in alkenes. Many double bonds exist betw ...

Isomers

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.
