A bilayer is a structural arrangement of two parallel layers of molecules, typically found in biological systems such as cell membranes. The most common example is the phospholipid bilayer that forms the basic structure of the plasma membrane in living cells. In this arrangement, phospholipid molecules are organized so that their hydrophilic (water-attracting) heads face outward toward the aqueous environment, while their hydrophobic (water-repelling) tails face inward, away from water. This creates a stable barrier between the inside and outside of the cell.
The bilayer is not rigid; it is fluid and dynamic, allowing proteins, lipids, and other molecules to move within it. This fluidity is crucial for various cellular processes such as transport of substances, cell signaling, and membrane repair. Embedded proteins within the bilayer serve important roles, including acting as channels, receptors, and enzymes.
