Glycerophospholipids
Glycerophospholipids are a type of fat molecule that form a major part of cell membranes. They consist of two fatty acid chains attached to a glycerol backbone, which also connects to a phosphate group and often a small charged or polar molecule. This structure makes them amphipathic—having both water-loving (polar) and water-fearing (nonpolar) parts—allowing them to create a flexible, protective barrier around cells. Glycerophospholipids are essential for maintaining cell integrity, facilitating communication between cells, and serving as precursors for other signaling molecules.
