| Common Name | Octadecadienoate |
|---|
| Description | Octadecadienoate belongs to the class of organic compounds known as lineolic acids and derivatives. These are derivatives of lineolic acid. Lineolic acid is a polyunsaturated omega-6 18 carbon long fatty acid, with two CC double bonds at the 9- and 12-positions. Octadecadienoate is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. |
