Cellulose, glycogen, and starch are polysaccharides. The results indicate that the presence of a benzene ring in saccharin, benzene sulfonic acid and benzothiazole cause these molecules to move from the electrolyte to the electrode surface and, by blocking the electrode surface, enhance the grain size and produce nickel coatings with an average grain size below 50 nm. Raffinose, a trisaccharide found in beans and sugar beets, contains D-galactose, D-glucose, and D-fructose. Electrochem., 2011, vol.

In an ether functional group, a central oxygen is bonded to two carbons. However, saccharin and its derivatives offer other opportunities and challenges to the synthetic chemists and biologist for the appropriate use of the same in different way, and we believe that these opportunities will never end because these catalysts will indeed form a huge source for catalytic strategies.
