Cholesterol molecules, although less abundant than glycerophospholipids, account for about 20 percent of the lipids in animal cell plasma membranes. However, cholesterol is not present in ...

This protein transfers cholesterol from the gut lumen to the plasma membrane of intestinal cells, initiating absorption. However, until recently, how cholesterol moves from this initial point to ...

This lipid abundance asymmetry is enabled by the unique properties of cholesterol and endows ... of cell biology by showing that the plasma membrane, the flexible bilayer that surrounds the ...
