%X Through its electron tunnelling, liver Ferritin of Dasyatis Akajei(DALF) directly picked the reduction electrons up from the platinum electrode for releasing iron. The heme not only bound to the ferritin to constitute a molecule of DALF-heme, called DALFH and to form a structure of electron-tunnel-heme, but also accelerated the rate that DALF received the electron from the electrode for increasing rate of iron release. Using a reducer of ascorbic acid, similar rates of iron release from both DALFH and DALF were observed. DALF was shown not only to obtaining the reduction electrons but also in accelerating the rate of iron release under aerobic environments, suggesting that the protein shell in the ferritin has two electron tunnels with different redox potentials.
