Figure 18. Steady-state composition of different membrane compartments of a mammalian cell.

The lipid composition of different membranes of the rat liver is variable. The individual graphs shows the lipid composition of the main phospholipids of a specific membrane compartment expressed as a percentage of the total phospholipid. Some minor lipids are not shown and are referred to as ‘others’. Some of the key minor lipids present in a particular compartment are included in the figure. Abbreviation: Chol, cholesterol.
