THE hemoglobin is a protein that is present inside the Red Cells (red blood cells) and whose main function is to transport oxygen from the lungs to the body's cells. It is hemoglobin that gives red blood cells their red color.
The word "hemoglobin" comes from the Greek Haima = blood and Globin, abbreviation for Globulin, from the Latin Globus = ball, perhaps because of the rounded shape of the red blood cells
As for your andmolecular structure, hemoglobin is composed of a heme pigment with iron in its interior and a protein called globin, formed by two pairs of polypeptide chains. These chains combine with each other, giving rise to different hemoglobin molecules.
Hemoglobin and Anemia
Anemia occurs when the amount of hemoglobin or red blood cells is below normal, and it can arise as a result of a lack of iron, zinc, vitamin B12 and protein.

Glycated Hemoglobin
Glycated or glycosylated hemoglobin is a type of hemoglobin that is naturally present in red blood cells and is useful for identifying high blood glucose levels for prolonged periods.
This type of hemoglobin is formed from non-enzymatic reactions between hemoglobin and glucose.
