Display Apolar side-chains
Apolar side-chains are shown ( Val, Leu,Ile). Note that they are on the inside and that each chain contributes one member of a pair.

Count Spacing between Apolars
Count the number of C-alpha atoms along the cyan backbone between adjacent pairsof apolar residues within the same helix.

Look down helix axis
View looking approxiamtely down the helix axis, showing the clustering of apolar side-chains between the chains.

Display Polar Side-Chains
Polar side-chains shown in red. Note that they are on the outside of the coiled-coil

Slab down helix axis
Use Ctrl-left mouse button to slab down through the structure. Notice (1) the apolar sidechains (dark green) are on the inside (2) the core is close-packed.
