Can myoglobin replace hemoglobin
WebAug 13, 2024 · Red blood cells contain the oxygen carrier protein hemoglobin. It is composed of four globular peptides, each containing a heme complex. In the center of each heme, lies iron (Figure 10.4.2). Eighty percent of the body's iron is bound to hemoglobin. In the muscle, iron is part of the oxygen-binding protein, myoglobin. WebJan 27, 2024 · The O 2 pressure at which half of the molecules in a solution of myoglobin are bound to O 2 (P 1/2) is about 1 mm Hg (1.3 × 10 −3 atm). Figure 6.8.2. 2. Oxygen Binding to Myoglobin and Hemoglobin. (a) The Fe 2+ ion in deoxymyoglobin is high spin, which makes it too large to fit into the “hole” in the center of the porphyrin.
