About the structure and biological function of oxiDPA Structure. Oxidized docosapentaenoic acids (oxiDPA) belong to the group of docosanoids within the fatty acyls. Their structure is based on docosanoic acid, a twenty-two carbon atoms long hydrocarbon chain with a carboxyl group. The chain contains five double bonds, from which their name derives. OxiDPAs may further … Continue reading Oxidized Docosa­pentaenoic Acid
