Which statements are true about cholesterol and it’s role in membrane fluidity
Cholesterol increases membrane fluidity in a membrane that otherwise contains mostly long-chain saturated fatty acids.
Cholesterol decreases membrane fluidity in areas called rafts, which contain large amounts of sphingolipids and cholesterol.
Cholesterol is generally buried in the bilayer, with its planar rings oriented toward the solvent and its hydroxyl group aligned with the fatty acid tails of the bilayer.
Cholesterol inhibits the crystallization that would otherwise occur in membranes rich in unsaturated fatty acids.
