MVV form a multilamellar arrangement with concentric phospholipid spheres as many unilamellar vesicles are produced within larger liposomes [37]. The phospholipid is essentially a triglyceride in which a fatty acid has been replaced by a phosphate group of some sort33. The phospholipids are not "true fats" because they have one of the fatty acids replaced by a phosphate group. The cell membrane contains a phospholipid bilayer, but the terms are not interchangeable. Antiphospholipid syndrome (APS) is a thrombo‑inflammatory disease propelled by circulating autoantibodies that recognize cell surface phospholipids and phospholipid binding proteins. Phospholipids [1] are a class of lipids whose molecule has a hydrophilic "head" containing a phosphate group and two hydrophobic "tails" derived from fatty acids, joined by an alcohol residue (usually a glycerol molecule). In the plasma membrane, PS is localized exclusively in the cytoplasmic leaflet where it forms part of protein docking sites necessary for the activation of several key signaling pathways. The ABCB4 gene (also known as MDR3 ) provides instructions for making a protein that helps move certain fats called phospholipids across the membranes of liver cells and release th. The fatty acid chains are hydrophobic and do not interact with water, whereas the phosphate-containing group is hydrophilic (because of its charge) and interacts readily with water. Phospholipide gehören zur Gruppe der Membranlipide. The "head" of the molecule contains the phosphate group and is hydrophilic, meaning that it will dissolve in water. They consist of a polar phosphate head group and two nonpolar fatty acid tails joined by a glycerol backbone.
