The interaction of inositol hexaphosphate with methaemoglobin.
1. Inositol hexaphosphate causes the shape of the oxidation-reduction equilibrium curve to become hyberbolic at acid pH values. 2. Inositol hexaphosphate also causes a decrease in the alkaline oxidation Bohr effect at these same pH values. 3. These results support the idea that inositol hexaphosphate causes methaemoglobin to take up the deoxyhaemoglobin quaternary structure at pH6.5.
