Figure 4
A section through the bilayer showing strong densities in the inner-leaflet hydrophobic core attributable to tight packing of the phospholipid hydrocarbon chains. The densities (HC) extend into the hydrophobic core about the same distance as would the sterol group of cholesterol. A matching slice through the model (PDB entry 6uwz) and two (manually inserted) sterol groups are superimposed on and next to one of the receptors to indicate the locations of two of the cholesterol sites identified in Fig. 3
