Electrochemical properties of ferritins with different core minerals.
| Reaction | Ferritin Core | mV | pH |
| Fe(OH)3 + e = Fe(OH)2 + OH− | Native HoSFa | −190 to −420 | 7.0–9.0 | Co(OH)3 + e = Co(OH)2 + OH− | Synthetic HoSFb | +50 | 7.0 | Mn(OH)3 + e = Mn(OH)2 + OH− | Synthetic HoSFb | +35 | 7.0 | Fe(OH)2(PO4) + e = Fe(OH)(PO4) + OH− | Native bacterialc ferritin | −430 | 7.0–9.0 | Fe(OH)2(PO4) + e = Fe(OH)(PO4) + OH− | Synthetic HoSF | −300 | 7.0 | Ni(OH)3 + e = Ni(OH)2 + OH− | Synthetic HoSF | −1000 | 7.0 |
