Explanation:
Detailed explanation-1: -Chol Increases Bending Rigidity of Unsaturated Lipid Bilayers. Chol is known to increase the bending rigidity of saturated lipid membranes (23, 24) through increased packing density and bilayer thickness (35). Yet studies of unsaturated lipids, such as DOPC, have shown surprisingly different trends.
Detailed explanation-2: -On the biophysical front, cholesterol significantly increases the order of the lipid packing, lowers the membrane permeability, and maintains membrane fluidity by forming liquid-ordered–phase lipid rafts.
