WebThe function of hemoglobin is the transport of oxygen to the tissues from the lungs. When oxygen is associated with the molecule it is termed oxyhemoglobin (OHb), whilst in the absence of oxygen it is termed deoxyhemoglobin or reduced hemoglobin (RHb). In these forms iron is present as iron (II). WebAug 13, 2024 · Video 11.4. 1: Oxygen Transport. Watch this video to view how hemoglobin in red blood cells transports oxygen to all cells in the body. Dietary iron comes in two forms, as heme iron or as nonheme iron. The bioavailability of iron is highly dependent on dietary sources and the form of iron.
WebIn both cases, the coordinated metal ions are probably the sites of catalytic activity. Hemoglobin also contains iron-porphyrin complexes, its role as an oxygen carrier being related to the ability of the iron atoms to coordinate oxygen molecules reversibly.
