In the following model, the carbon atoms are dark gray, hydrogen is cyan and oxygen is red.
In the following model, the carbon atoms are dark gray, hydrogen is cyan, oxygen is red, nitrogen is dark blue and phosphorus is orange.
The light blue (cyan) network above and below the bilayer consists of water molecules (not drawn to size). Red atoms are oxygen, dark gray are carbon and orange are phosphorous. Nitrogen atoms are dark blue, but none are evident. The hydrogen atoms on the alkyl chains are not shown.
