Phospholipid Bilayer | Definition, Function & Structure

The cellular membrane in humans is a sophisticated structure primarily comprised of a lipid bilayer housing embedded proteins. This bilayer consists of two layers of phospholipids arranged so that their hydrophobic tails face inward and hydrophilic heads face outward. This arrangement forms a protective barrier separating the cell’s interior from its external surroundings. Embedded within the lipid bilayer are proteins that play vital roles in various cellular functions, including the transport
