Used as a synthetic phospholipid analog in research settings, particularly in studies involving cell membrane dynamics and signal transduction. It serves as a substrate or modulator in enzymatic assays involving phospholipases, especially phospholipase D and phospholipase A2, due to its structurally defined acyl chains. Its short acyl chains (hexanoyl) compared to natural long-chain phospholipids enhance water solubility, making it suitable for in vitro experiments where micelle formation or membrane incorporation is needed without complex delivery systems. Also employed in the development and testing of lipid-based drug delivery systems and liposomal formulations, where controlled membrane composition is critical. Its serine head group allows it to mimic biological phosphatidylserine, enabling use in apoptosis studies and protein-lipid interaction assays.
