- Haemoglobin
- made from four protein molecules
- globulin chains
- Two alpha globulin chains and two beta globulin chains
- In fetuses and infants, beta chains are not common and the hemoglobin molecule is made up of two alpha chains and two gamma chains
- As the infant grows, the gamma chains are gradually replaced by beta chains, forming the adult hemoglobin structure.
- Heme molecule
- A globulin chain that contains an important central structure
- Embedded within the heme molecule is iron that is vital in transporting oxygen and carbon dioxide in our blood.
- The iron contained in hemoglobin is also responsible for the red color of blood
- A globulin chain that contains an important central structure
- important role in maintaining the shape of the red blood cells
- In their natural shape, red blood cells are round with narrow centers resembling a donut without a hole in the middle.
- Abnormal hemoglobin structure can, therefore, disrupt the shape of red blood cells and impede their function and flow through blood vessels.

- consists mostly of subunits
- folded chains of a large number of amino acids
- Polypepties
- The amino acid sequence of any polypeptide created by a cell is in turn determined by the stretches of DNA called genes
- amino acid sequence that determines the protein's chemical properties and function.

- folded chains of a large number of amino acids
- Hemoglobin has a quaternary structure characteristic of many multi-subunit globular proteins
- comes from its four subunits in roughly a tetrahedral arrangement
- made from four protein molecules
