WebThis is in the range of pO 2 in the tissues (non-respiring cells), so much of the oxygen released by hemoglobin will be taken up by myoglobin (which has a higher affinity for O 2 ) and stored. The P 50 for myoglobin is ~0- 0 kPa – this is in the range of pO 2 concentration in respiring cells, so myoglobin will release most of its oxygen at and below this pO 2. WebFerritin stores iron as ferrihydrite inside a shell composed of H and L protein chains. H chains contain ferroxidase centres catalysing Fe2+ oxidation, while L chains lack these centres but seem to promote ferrihydrite nucleation.
