Abstract: The direct electrochemistry of cytoclirome Cat gold electrodes modified with different monosaccharides was investigated.It was found that all the five monosaccharides studied are effective promoters for the direct electrochemistry of cytoclirome C.However, the promotion effect strongly depends on the dipping time and concentration of monosaccharides in the modification procedure of the gold electrode and the performance of the monosaccharide-modified gold electrodes is not stable because of the weak adsorption of the monosaccharide molecules on the gold surface.These results indicate that the coverage of promoter molecules on the surface of the gold electrode is an important factor to affect the promotion effect of promoters.

Key words: Cytocllrome C, Monosaccharide, Promotor
