Haemoglobin. Computer model of the haemoglobin molecule that transports oxygen around the body in red blood cells. It has four iron-containing haem groups (coloured spheres). The rest of the haemoglobin structure consists of four globin proteins (amino acid chains,coils). Each globin protein is wrapped around a haem group,protecting it from being oxidised and destroyed by the oxygen it is intended to transport. The structure of the haem molecules is not clearly seen,but the atoms are colour-coded: carbon (yellow),oxygen (red),nitrogen (blue) and iron (green). It is this iron atom that reversibly bonds to oxygen and carbon dioxide in the blood | |
