| 中文摘要 | investigation of the redox thermodynamics of horse heart cytochrome c at bare glassy carbon electrodes has been performed using cyclic voltammetry with a nonisothermal electrochemical cell. the thermodynamic parameters of the electron-transfer reaction of cytochrome c have been estimated in different component buffer solutions. the change deltas(re)-degrees in reaction center entropy and the formal potential e-degrees' (at 25-degrees-c, vs. standard hydrogen electrode (she)) for cytochrome c are found to be -64.1 j k-1 mol-1 and 0.251 v in phosphate buffer, -64.8 j k-1 mol-1 and 0.257 v in tris + hcl buffer, -65.6 j k-1 mol-1 and 0.261 v in tris+ch3cooh buffer (ph 7.0, ionic strength 100 mm). the temperature dependence of the formal potential obtained in phosphate buffer with or without nacl in the range 5-55-degrees-c shows biphase characteristics in an alkaline solution with an intersection point at ca. 44-degrees-c or 42-degrees-c, which should be due to a structural change in the protein moiety of cytochrome c. however, in acidic and neutral solutions only a monotonic relationship between e-degrees' and temperature is observed. the effect of the buffer component on e-degrees' for cytochrome c is also discussed. |
