The primary components of the lipid bilayer are phospholipids, cholesterol, and proteins. 1. Phospholipids: These are the main structural components, with a hydrophilic head and hydrophobic tails. 2. Cholesterol: It is interspersed within the bilayer, contributing to membrane fluidity and stability. 3. Proteins: Integral and peripheral proteins are embedded in or associated with the lipid bilayer, playing roles in transport, signal transduction, and cell recognition.
