Used in biomedical research as a model compound for studying phospholipid metabolism and cell membrane dynamics. Serves as a precursor in the synthesis of phosphatidylcholine, a major component of biological membranes. Employed in lipid signaling studies due to its role in choline phosphate pathways. Also utilized in the development and testing of drug delivery systems, particularly liposomal formulations, where it helps stabilize lipid bilayers. Its calcium salt form enhances solubility and compatibility in physiological buffers, making it suitable for in vitro and cellular assays.
