Model of lipid bilayer

Model of a lipid bilayer membrane

(Adapted from a Rasmol script by Eric Martz)

A phospholipid bilayer with added water molecules, relaxed to the liquid crystalline state by molecular dynamics

Phosphorus atoms (orange).

Nitrogens (blue). Notice the positions of the nitrogens relative to the phosphorus.

Lipids, CPK coloring.

Waters (CPK coloring (O-atoms red, H-atoms white).

Wireframe model.

 This PDB file was modified by Eric Martz as follows:
 1. A portion of the water of the top leaflet was removed (X > 7)
     (hence the designation 'cutaway' or 'cut').
 2. Every second remaining water molecule was removed (hence the
     designation '2') to enable 'seeing through' the water layer.
