Which among the following is the function of cholesterol in the Plasmalemma:
The fluidity of the lipid bilayer is decreased in 3 ways: (1) By lowering the temperature, (2) By increasing the saturation of the fatty acyl tails of the phospholipid molecules, and (3) By increasing the membrane's cholesterol content Cholesterol interacts with phospholipids containing unsaturated fatty acyl chains, compacting them and constraining their motion in bilayers, hence decreases the fluidity.
Increase fluidity of the lipid bilayer.
Decrease fluidity of the lipid bilayer
Facilitate the diffusion of ions through the lipid bilayer
Assist in the transpo of hormones across the lipid bilayer
Cholesterol synthesis and bile acids
