Widely used in biochemical research as a key intermediate in phospholipid metabolism. Serves as a precursor in the synthesis of phosphatidylcholine, a major component of cell membranes. Plays a role in signal transduction pathways and is involved in the regulation of cellular processes such as proliferation and apoptosis. Commonly used in cell culture studies to investigate membrane biosynthesis and lipid signaling. Also utilized in the development of liposomal drug delivery systems due to its role in forming stable phospholipid bilayers.
