Encyclopedia: Lipid bilayer (657 words)
In biology and chemistry, a lipid bilayer is a membrane or zone of a membrane composed of lipid molecules (usually phospholipids).
The lipid bilayer is the foundation of all biological membranes, including cell membranes, and is a prerequisite of cell-based life.
The bilayer is composed of two opposing layers of lipid molecules arranged so that their hydrocarbon tails face one another to form the oily bilayer core, while their electrically charged or polar heads face the watery or "aqueous" solutions on either side of the membrane.
