In cells like the endometrial cells, mesangial cells, and others, hemoglobin functions as a regulator that can metabolize iron. Here, it does not display its oxygen-carrying capacity. You must have seen the red color of blood. And everyone knows that this red color is because of the hemoglobin present in the blood. But have you ever wondered how or why is that so? It is because of the binding of the iron present in the heme with the oxygen.
