1,2-Dipalmitoyl-sn-glycero-3-phospho-rac-glycerol sodium salt (CAS 67232-81-9)

1,2-Dipalmitoyl-sn-glycero-3-phospho-rac-glycerol sodium salt (DPPG) is a phospholipid that plays a significant role in the study of lipid bilayers and membrane dynamics. DPPG, composed of two palmitic acid chains esterified to a glycerol backbone with a phosphoglycerol head group, is widely used as a model phospholipid in biophysical and biochemical research. Its structure and properties make it an ideal component for mimicking biological membranes in studies of membrane fluidity, phase behavior, and lipid-protein interactions. DPPG is particularly valuable in research focused on the structural organization and functional properties of lipid bilayers, providing insights into the biophysical characteristics of cell membranes. Researchers use DPPG to investigate the effects of lipid composition on membrane permeability, surface charge, and interactions with ions and other biomolecules. It is also employed in the study of liposomes and vesicles, which are essential models for drug delivery systems and understanding membrane fusion processes. Additionally, DPPG is used in experiments to explore the mechanisms of membrane-associated proteins and peptides, including their insertion, folding, and function within lipid bilayers. Overall, DPPG serves as a crucial tool in membrane biophysics and cell biology, enhancing our understanding of lipid membrane structure and function.
