Hemoglobin (or haemoglobin) is a protein in red blood cells which contains iron it is used to transport oxygen around the human body hemoglobin is found in the red. Normal hemoglobin function important characteristics of the hemoglobin molecule : when fully saturated, each gram of hemoglobin binds 134 ml of oxygen the degree of saturation is related to the oxygen tension (po2), which normally ranges from 100 mm hg in arterial blood to about 35 mm hg in veins. Hemoglobin synthesis requires the coordinated production of heme and globin the prosthetic group that mediates reversible binding of oxygen by hemoglobin is the protein that surrounds and protects the heme molecule in the cytosol of the cell (figure 1.
