Used in biochemical research to study cell signaling pathways, particularly those involving phosphoinositides. It serves as a substrate for enzymes like phospholipase C and phosphatidylinositol kinases, helping to understand lipid metabolism and membrane dynamics. Applied in vitro to investigate protein-lipid interactions and the role of phosphoinositides in cellular processes such as vesicle trafficking and cytoskeletal organization. Also utilized in drug discovery to screen compounds targeting lipid-related signaling pathways. Its synthetic form allows controlled experimentation in lipid biology studies.
