Such a complex structure of hemoglobin and provides its main function in the transfer of oxygen and maintenance of cellular respiration. It is the trace element of trivalent iron that attaches an oxygen molecule, and then gives it to the cell during oxidation. The hemoglobin molecule itself contains a globin protein on which the heme is configured - it is a complex prostacyclic compound that contains in the center an iron molecule. Erythrocytes provide the transfer of the oxygen molecule from the lungs to all cells of the female body precisely due to the content of hemoglobin in its composition. Hemoglobin is the main component of erythrocytes - red blood cells. Rochester (NY): University of Rochester Medical Center c2022.
