Widely used in membrane biology research due to its role in forming the structural basis of cell membranes. It supports the formation of lamellar and non-lamellar phases, influencing membrane curvature and fusion processes. Commonly employed in liposome preparation for drug delivery systems, where it enhances membrane stability and promotes cellular uptake. Also utilized in studies of protein-lipid interactions, especially with membrane-associated proteins that require specific lipid environments for proper function. Its presence is critical in bacterial membrane models, particularly in mimicking the inner membrane of E. coli for functional and biophysical studies. Frequently used in enzyme assays involving phospholipases and lipid kinases where it acts as a natural substrate.
