Self-organization of phospholipids: a spherical liposome, a micelle and a lipid bilayer.
A biological membrane or biomembrane is an enclosing or separating membrane that acts as a selective barrier, within or around a cell. It consist of a lipid bilayer with embedded proteins that may constitute
close to 50% of membrane content. The cellular membranes should not be confused with isolating tissues formed by layers of cells, such as mucous and basement membranes. 390
