Overall Architecture of Hemoglobin.

The hemoglobin tetramer is shown using the Cartoon display.
The heme groups are shown as Spacefill with CPK coloring.

All four subunits are entirely a-helical; the polypeptide chains are colored separately:
a1: Blue       b1: Cyan
a2: Green     b2: Yellow

Viewing tips:
Use the buttons to the right of the image to show only portions of the structure; then use the Chime menu to display or color the molecule. The rotate buttons act on the entire structure. Remove the distance monitors with a second click.
