Chemistry of Oxygen Transport in Blood Tutorial
- Oxygen is transported around the body in blood by the complex molecule haemoglogin (hemoglobin), a globular protein which has a central iron atom.
- When haemoglobin (hemoglobin) reacts with oxygen, oxyhaemoglobin (oxyhemoglobin) is formed
- The oxygenation of blood is an equilibrium reaction
- The pH of blood is maintained at around 7.4 by a series of buffer systems
- Acidosis occurs when the pH of blood falls below 7.4
- Alkalosis occurs when the pH of blood rises above 7.4
- Carbon monoxide, CO, also readily reacts with haemoglobin (hemoglobin) which can result in carbon monoxide poisoning
