- Haemoglobin
- Properties
- Basic Shape is globular
- The tertiary structure of the molecule is wound into ? helices
- Contains a haem prosthetic group
- Role
- Carries oxygen in the blood from the respiratory organs to the rest of the body.
- Oxygen required in the process of cellular respiration
- Releases the oxygen to permit aerobic respiration to provide energy
- Plays an important role in maintaining the shape of the red blood cells.
- Carries oxygen in the blood from the respiratory organs to the rest of the body.
- Structure
- Its made up of four protein molecules (globulin chains) that are connected together.
- Each globulin chain contains an important central structure called the heme molecule
- Iron embedded in the heme molecule
- Vital in transporting oxygen and carbon dioxide in our blood.
- Iron is responsible for the red color of blood.
- Iron embedded in the heme molecule
- Each globulin chain contains an important central structure called the heme molecule
- The normal adult molecule contains two alpha-globulin chains and two beta-globulin chains
- In fetuses and infants, beta chains are not common and the 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
- Its made up of four protein molecules (globulin chains) that are connected together.
