Asymmetrical arrangement of

phospholipids in plasma membrane

„ ATP-dependent phospholipid translocase

Molecular Cell Biology, Lodish et al., 4th edition.

Figure 2—1. The ultrastructure and molecular organization (right)

of the cell membrane. The dark lines at left represent the two dense

layers observed in the electron microscope; these are caused by the

deposit of osmium in the hydrophilic portions of the phospholipid

molecules.
