Haem is a ______ complex with a _______ ligand. What is haemoglobin? How does it work and what is the problem? |
Iron(II) Multidentate A nitrogen in a globin complex acts as a ligand with the iron. Oxygen forms a coordinate bond to the iron (II) which allows it to be transported in the the blood. Bond is weak so oxygen can be given up to cells CO replaces the oxygen as it's a better ligand. Bonds irreversibly so destroys the haemoglobin's oxygen-carrying capacity |
