WebCholesterol orders lipids and induces phase separation and curvature changes in fluid lipid bilayers Cholesterol has a unique structure of four fused hydrocarbon rings with a polar hydroxyl group at one end and an eight-carbon branched aliphatic tail at the other end. WebOn 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. However, direct observation of any influence on membrane chemistry related to these cholesterol-induced physical properties has been absent.
