Input (English): Gower and Portland are embryonic types of this molecule and the Bart form results in its namesake H disease, which is a type of thalassemia. The change between its tense and relaxed structure results from a 15 degree rotation between its two alpha-beta dimers. Its ability to neutralize hydrogen ions is described by the Haldane effect, while the impact of pH on it is described by the Bohr effect. Impacted by 2,3-DPG, a variant of this protein has a valine substituted for a glutamic acid. For 10 points, name this iron-containing component of red blood cells that carry oxygen.
Output (English): Science
