Explain how the structure of cholesterol enables it to perform structural and functional roles within membranes

Cell membrane is comprised of phospholipids (its major component) which can create lipid bilayers because of their water attracting characteristics. Another lipid inside the cell membrane is cholesterol, which makes the cell membrane more fluid. Cholesterol is a waxy fat-like substance found in all cells of the body.
