Lipid bilayers are fundamental structural components of cell membranes, composed of two layers of phospholipids with hydrophilic heads facing outward and hydrophobic tails inward, creating a semi-permeable barrier. This structure is crucial for maintaining cellular integrity, facilitating communication, and regulating the movement of substances in and out of cells.
