1,2-O,O-Dihexadecyl-rac-glycero-3-phosphoethanolamine

1,2-O,O-Dihexadecyl-rac-glycero-3-phosphocholine is a synthetic phospholipid extensively used in biophysical and biochemical research, particularly for studying the structure and dynamics of lipid bilayers. This molecule is composed of a glycerol backbone to which two hexadecyl (cetyl) chains are attached at the sn-1 and sn-2 positions, imparting significant hydrophobic properties and stability to the lipid bilayers it forms. The sn-3 position is occupied by a phosphocholine group, providing a positively charged headgroup that enhances the molecule′s solubility and interaction with aqueous environments. This configuration makes it an ideal candidate for creating model membranes that mimic the characteristics of natural biological membranes, facilitating studies on membrane fluidity, phase behavior, and interactions with proteins and other biomolecules. Researchers utilize 1,2-O,O-Dihexadecyl-rac-glycero-3-phosphocholine to investigate fundamental cellular processes such as signaling, transport, and membrane fusion, without involving any direct medical, therapeutic, or pharmaceutical applications, thereby contributing to a deeper understanding of cellular structure and function in a purely scientific context.
