Docosahexaenoic acid incorporation into membrane phospholipids

Incorporation of docosahexaenoic acid into membrane phospholipids, particularly glycerophospholipids such as phosphatidylethanolamine (PE) and phosphatidylserine (PS), substantially influences the fluidity and flexibility of cellular membranes[1][2]. DHA is highly enriched in the membranes of neuronal, retinal, cardiac, and reproductive tissues, where its unique structure due to multiple cis double bonds imparts increased membrane curvature and flexibility, facilitating dynamic processes such as membrane fusion and fission, and modulating conformational changes in membrane proteins[1]. In neurons, increased incorporation of DHA into PS promotes neuronal survival by supporting activation of the Akt signaling pathway, which reduces apoptotic cell death; conversely, depletion of DHA increases neuronal vulnerability[2]. The incorporation process is not a classical molecular therapeutic target such as a receptor or enzyme, but a physiological and metabolic phenomenon critical for normal tissue function and implicated in the pathophysiology of neurodegenerative, cardiovascular, and visual diseases[1][2].
