Hemoglobin synthesis requires the coordinated production of heme and globin. Heme is the prosthetic group that mediates reversible binding of oxygen by hemoglobin. Globin is the protein that surrounds and protects the heme molecule.

The haemoglobin molecule contains two different globin chains and haem. These three components are synthesized in all crythroid cells in equivalent amounts.
It seems that this coordination of the equivalent haem and globin chain production takes place in the cytoplasm and is not under genetic control because haem and globin syntheses are also Describe factors involved in the regulation of erythrocyte production, including substances needed for erythropoiesis and hemoglobin synthesis.

Erythropoiesis (RBC production) Mature erythrocytes are derived from committed erythroid proginator cells through a series of mitotic divisions and maturation phases.
Erythropoietin, a humoral agent produced mainly by the kidneys stimulates erythropoiesis by acting on committed stem Erythropoiesis in the fetal mouse provides a model to study several important aspects of the regulation of cell differentiation and differentiated protein synthesis.
Changes in the patterns of hemoglobins formed during fetal and postfetal development are shown to be associated with the substitution of the liver erythroid cell line. In the course of differentiation of yolk sac erythroid cells Human haemoglobin is made up of two chains which combine from four different polypeptide chains formed in varying ratios in different periods of the life cycle.
During the life span of humans the following haemoglobins are formed: embryonic haemoglobins Gower 1 and 2, foetal haemoglobin F and two adult haemoglobins A and :// Erythropoiesis is a tightly-regulated and complex process originating in the bone marrow from a multipotent stem cell and terminating in a mature, enucleated erythrocyte.
