1-Stearoyl-sn-glycero-3-phospho-sn-1-glycerol sodium salt

1-Stearoyl-sn-glycero-3-phospho-sn-1-glycerol sodium salt is a synthetic phospholipid extensively used in biophysical research to investigate the properties and behaviors of lipid bilayers that mimic biological membranes. This chemical features a stearoyl fatty acid chain linked to the sn-1 position of a glycerol backbone, with a phosphoglycerol group at the sn-3 position, and enhanced solubility provided by the sodium salt. The structure of this molecule allows for detailed studies on the impact of fatty acid saturation on membrane dynamics, including fluidity, phase behavior, and the interaction with other lipids and proteins. It is particularly useful for exploring how specific lipid compositions influence the structural integrity and functional capabilities of cell membranes. Research utilizing this compound is vital for understanding the mechanisms of lipid bilayer assembly and the role of phosphoglycerol in mediating membrane curvature and vesicle formation. These studies contribute to a broader comprehension of lipid-mediated cellular processes such as signaling and transport, offering insights purely for scientific inquiry. The use of this phospholipid helps decipher fundamental cellular mechanisms, thereby advancing our knowledge of membrane biophysics and cell biology.
