Description
Phosphoglyceride (PG) are also referred as glycerophospholipid. It is an important component of membrane bilayers. It has three-carbon backbone of glycerol, two long-chain fatty acids, esterified to hydroxyl groups on carbons 1 and 2 of the glycerol and phosphoric acid esterified to the C3 hydroxyl group of glycerol. It is found at high levels in the membranes of all cells and at low levels in fat stores16:0 PG has been used as a component in internal lipid standard mixture for matrix-assisted laser desorption/ionization (MALDI)- fourier-transform ion cyclotron resonance (FTICR)- mass spectrometry (MS) analysis. It is also suitable to use in liposome flotation assay to study the specificity of protein-lipid interaction
