1. Structural component: Cholesterol helps maintain the fluidity and stability of the cell membrane by interacting with phospholipids and preventing them from packing too closely together.
2. Regulation of membrane fluidity: Cholesterol acts as a buffer, preventing the cell membrane from becoming too rigid or too fluid in response to changes in temperature.
3. Cell signaling: Cholesterol plays a role in cell signaling by interacting with membrane proteins and influencing their activity. It can also serve as a precursor for the synthesis of signaling molecules such as steroid hormones.
4. Protection: Cholesterol helps protect the cell membrane from damage by stabilizing it and reducing its susceptibility to oxidative stress and damage from harmful substances.

1. Structural component: Cholesterol is a major component of the lipid bilayer of cell membranes, helping to maintain their structural integrity.
2. Fluidity regulator: Cholesterol modulates the fluidity of the membrane by reducing its permeability to ions and other small molecules. It prevents the membrane from becoming too rigid or too fluid.
3. Signal transduction: Cholesterol is involved in signal transduction pathways by binding to and regulating the activity of membrane proteins. It can influence the activity of G proteins, ion channels, and other signaling molecules.
4. Lipid raft formation: Cholesterol is enriched in specialized membrane domains called lipid rafts, which are involved in various cellular functions such as cell signaling, protein sorting, and endocytosis.
