Oxyhemoglobin: β chains are blue and cyan. α chains are red and salmon. On click, β-His97 is colored yellow, α-Thr41 is colored magenta, and α-Pro44 is colored green. On click, the oxyhemoglobin is tilted for a better view. On click, the two helices are highlightedStructure of human oxyhaemoglobin at 2.1 A resolution. Shaanan B.

On click, the deoxyhemoglobin is tilted for a better view.
On click, the two helices are highlighted. Notice the difference in packing.
