Relaxed and tense hemoglobin
WebA number of synthetic molecules also bind to Hb to alter its allosteric activity. Our purpose is to review the current state of Hb structure and function that involves ensemble of tense and relaxed hemoglobin states and the dynamic equilibrium of the multistate due to the binding of endogenous heterotropic or synthetic allosteric effectors. WebHb: hemoglobin; O 2: oxygen gas; Hb F: fetal hemoglobin; R state: relaxed state of hemoglobin; T state: tense state of hemoglobin. * The ferric hemes of methemoglobin do …
