1. Cholesterol helps maintain the fluidity and stability of the cell membrane by preventing the phospholipid molecules from packing too closely together. This allows the membrane to remain flexible and responsive to changes in the environment.

2. Cholesterol also plays a role in regulating the permeability of the cell membrane, controlling the movement of molecules in and out of the cell. It helps to create a barrier that selectively allows certain substances to pass through while blocking others, thus maintaining the integrity and function of the cell.

1. Structural component: Cholesterol is an important structural component of cell membranes, where it helps to maintain membrane fluidity and integrity. It interacts with the phospholipids and proteins in the membrane, influencing its curvature and thickness.

2. Modulator of membrane fluidity: Cholesterol plays a crucial role in modulating the fluidity of the cell membrane. At low levels, cholesterol increases membrane fluidity by preventing the tight packing of phospholipids. At higher levels, cholesterol can reduce membrane fluidity by increasing the thickness and rigidity of the membrane.
