Used in lipid research as a key intermediate in the synthesis of more complex phospholipids, particularly in studies involving glycerophospholipid metabolism. It serves as a substrate for enzymes such as acyltransferases and phospholipases, helping to elucidate biochemical pathways in cell membrane dynamics. Also employed in the formulation of model membrane systems to investigate membrane protein interactions and lipid signaling mechanisms. Its sodium salt form enhances solubility in aqueous buffers, making it suitable for in vitro assays and enzymatic studies.
