Used in research as a model phospholipid for studying cell membrane structure and dynamics due to its natural occurrence in biological membranes. Commonly employed in liposome formulation for drug delivery systems, where it helps mimic the fluidity and permeability of real cell membranes. Also utilized in studies of lipid-protein interactions and membrane fusion processes. Its unsaturated nature makes it suitable for investigating oxidative stress and lipid peroxidation in cellular models.
