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 encompass multiple hydroxy groups as well as other oxygen containing substituents.

Function. Oxidized docosapentaenoic acids are important to neurodevelopment and neuroprotection, as well as cardiovascular disease prevention. OxiDPAs are biosynthetic intermediates to a variety of other docosanoid lipids. Further, oxiDPA lipids may be linked to some of the beneficial effects of dietary omega-3 fatty acids.
