Thin bimolecular sheet of mainly phospholipid molecules that forms the structural basis for all cell membranes. The two layers of lipid molecules are packed with their hydrophobic tails pointing inward and their hydrophilic heads outward, exposed to water.
a structure formed by phospholipids in an aqueous solution
cell membrane made up of two layers of fat molecules and embedded proteins.
comprises two layers of, typically amphiphilic, molecular arrays arranged oposite to each other with a common hydrophobic bilayer interior and two hydrophilic surfaces.
a membrane structure that consists of two back-to-back layers of lipids, in each of which the polar head groups on each side face the water and the nonpolar tails lie in the center of the membrane.
A lipid bilayer or bilayer lipid membrane is a membrane or zone of a membrane composed of lipid molecules (usually phospholipids). The lipid bilayer is a critical component of all biological membranes, including cell membranes, and so is absolutely essential for all life on earth. Its essential structure was discovered in 1925 by two Dutch physicians, E.Gorter and F.Grendel, whilst comparing the surface area of human erythrocytes with that of the isolated lipids in a Langmuir Blodgett trough.
