1,2-dimyristoyl-d54-sn-glycero-3-[phospho-rac-(1-glycerol)] (sodium salt)

1,2-dimyristoyl-d54-sn-glycero-3-[phospho-rac-(1-glycerol)] (sodium salt) is a synthetic lipid molecule used in various research fields, particularly in the study of membrane structure and function. It is a deuterated derivative of 1,2-dimyristoyl-sn-glycero-3-phosphoglycerol (DMPG), which is a major component of biological membranes. The “d54” in the name of the molecule refers to the isotopic labeling of the molecule with deuterium. This labeling is useful in nuclear magnetic resonance (NMR) spectroscopy experiments, as it can provide additional information on the molecular structure and dynamics. The molecule is typically supplied as a white powder and is soluble in water. It is commonly used as a model lipid in liposome preparation and membrane studies. It is also used in drug delivery systems and in the development of new lipid-based therapies. From a chemical perspective, the molecule is a glycerophospholipid, consisting of a glycerol backbone, two myristic acid chains, and a phosphoglycerol head group with a sodium ion. The two myristic acid chains are saturated fatty acids, meaning they do not contain any double bonds in their carbon chains. The molecule has a net negative charge due to the presence of the phosphate and glycerol groups.
