Hemoglobin is the protein particle in red platelets that conveys oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs. Hemoglobin is comprised of four protein particles (globulin chains) that are associated together. The typical grown-up hemoglobin (condensed Hgb or Hb) particle contains two alpha-globulin chains and two beta-globulin chains. In hatchlings and newborn children, beta chains are not normal and the hemoglobin particle is comprised of two alpha chains and two gamma chains. As the newborn child develops, the gamma chains are step by step supplanted by beta chains, shaping the grown-up hemoglobin structure. Every globulin chain contains a significant iron-containing porphyrin compound named heme. Inserted inside the heme compound is an iron molecule that is crucial in moving oxygen and carbon dioxide in our blood. The iron contained in hemoglobin is likewise answerable for the red shade of blood. Hemoglobin additionally assumes a significant job fit as a fiddle of the red platelets. In their common shape, red platelets are round with restricted focuses taking after a doughnut without an opening in the center. Anomalous hemoglobin structure can, in this manner, upset the state of red platelets and obstruct their capacity and move through veins
