About the structure and biological function of oxiODE Structure. Oxidized octadecadienoic acids (oxiODE) belong to the group of octadecanoids within the fatty acyls. Their structure is based on octadecanoic acid, an eighteen carbon atoms long hydrocarbon chain with a carboxyl group. The chain contains two double bonds, from which their name derives. OxiODEs may further … Continue reading Oxidized Octadeca­dienoic Acid
