Oxyhemoglobin and deoxyhemoglobin
Hemoglobin carrying oxygen is referred to as oxyhemoglobin (oxyHb)'. Each Hb molecule can bind 4 oxygen molecules. After the release of oxygen, we speak of deoxyhemoglobin (deoxyHb)'. In both forms, iron is divalent, as only hemoglobin containing FeII+ can reversibly bind and transport an oxygen molecule. Oxygenation of the hemoglobin molecule changes the electron state of the FeII+-heme complex, which is manifested by a change in the color of the dark red shade typical of venous blood to the bright red color of arterial blood. In the human body, about 98.5%[1]oxygen bound to hemoglobin.
