Cholesterol Regulates Membrane Fluidity in Animal Cells

Cholesterol helps keep the cell membrane of eukaryotes stable and working.
It makes up 20 to 40% of the lipids in the plasma membrane and is a steroid, not a glyceride.
Its structure and position in the membrane let it regulate membrane fluidity as conditions change.

The Structure of Cholesterol Anchors It in the Bilayer

Hydrophobic region: most of the molecule is hydrophobic and sits among the hydrocarbon tails of the phospholipids in the membrane core.
