Witryna9 paź 2024 · Cholesterol represents around 25-30% of the plasma membrane and due to its chemical structure, it has the capacity to fit in spaces in the middle of the phospholipids and prevent the diffusion across the membrane of water-soluble molecules, thus reducing the permeability of the membrane. WitrynaAt low T's, cholesterol increases fluidity by preventing overly tight packing of the phospholipids . At higher T's, cholesterol decreases fluidity by pulling the phospholipids closer together so at medium T's, cholesterol is keeping the bilayer together but also preventing the phospholipids from overpacking.
