a comparison of the maximal stability of the cooperative structure of apomyoglobin which is 12 kj.mol-1 at 30 degrees c and ph close to neutral ones with the maximal stability of metmyoglobin which is 49 kj.mol-1 shows that the contribution of heme in the stabilization of the native myoglobin structure reaches 37 kj.mol-1 .
