Haemoglobin - "A molecule, found in red blood cells, composed of the iron-containing pigment haem and the protein globin. Each molecule contains four haem groups, each of which is bound to an iron atom. The haem groups bind reversibly with oxygen and this is the main way in which oxygen is transported in the blood of vertebrates and released to the tissues." (B125, B290)
