For better illustration of the structures at work, the structure shown will only contain one subunit. The <scene name='Sandbox_Reserved_695/Vgsc_alphabeta/2'>secondary structure</scene> includes alpha helices (blue) and beta strands (red). The <scene name='Sandbox_Reserved_695/Vgsc_hydrophobicpolar/2'>hydrophobicity</scene> of the structure reveals that the {{Template:ColorKey_Hydrophobic}} and {{Template:ColorKey_Polar}} residues | For better illustration of the structures at work, the structure shown will only contain one subunit.
