What is Indirect, Anodic Oxidation of D-glucitol in Aqueous Calcium Iodide about?

The anodic oxidation of aldcses in aqueous solurion, using platinum electrodes, yields fewer aldoses, and it has been assumed that progressive degradation proceeds through the corresponding aIdonic and aIduIosonic acids until the monosaccharide is completely converted into carbon dioxide' -s\_ Such degradation occurs even in non-aqueous media and, although aldcnic acids were not detected, their formation was presumed to be the first step6. However, when a platinum anode was used ir, a phosphate buffer (pH 7.4) in the potential range -0.75 to ;0.20 V, D-&conic acid was formed from D-&COSe and was not further oxidised, but was adsorbed on the electrode surface, thereby hindering the oxidation process'. Since ozone is produced in the electrolysis of aldoses', sr-keto compounds may be formed' and subsequently z-ketoaldonic acids which can undergo decarboxyIation to the next lower aldose.
