This is a [[Morphs#Linear_Interpolation|linear interpolation morph]] showing the oxygenation/deoxygenation of heme in the beta chain of human hemoglobin. Chain B of [[1hga]] (deoxygenated, 2.1 Å) was morphed to chain B of [[1hho]] (oxygenated, 2.1 Å). The two chains were aligned on three carbon atoms in the heme. | This is a [[Morphs#Linear_Interpolation|linear interpolation morph]] showing the oxygenation/deoxygenation of heme in the beta chain of human hemoglobin.

The two carboxy | The two carboxy groups on the heme, and one other carbon atom, were "frozen" because their positions in the two starting models differ for unimportant reasons, and their morph movements are distracting. | ||
