Membrane lipid structure and composition

Membrane lipid structure and composition refers to the array and arrangement of different lipid molecules—including phospholipids, glycolipids, cholesterol, and sphingolipids—that together form the lipid bilayer of biological membranes. This bilayer provides a barrier between cellular compartments, facilitates the compartmentalization of cellular processes, and regulates the fluidity and flexibility of membranes. Membrane lipids are amphipathic molecules, meaning each molecule has both hydrophobic and hydrophilic regions, which allows them to self-assemble into stable bilayers in aqueous environments. The inner and outer leaflets of membranes have distinctly different lipid compositions, reflecting specialized cellular functions. Changes and variations in membrane lipid composition are critical to multiple normal processes and diseases, but "membrane lipid structure and composition" itself is not a druggable or canonical therapeutic target; rather, specific types of membrane lipids, or enzymes regulating their synthesis or metabolism, may be targets.
