The Oxidation of Melezitose by Per-iodic Acid

Recent work by Richtmyer and the writer48 has confirmed this formula XV through a study of the oxidation of melezitose by per-iodic acid. They found that the oxidation resulted in the reduction of 4 moles of the acid to 4 moles of iodic acid for each mole of sugar, and the generation of 2 moles of formic acid no formaldehyde could be detected. It can be shown that these analytical measurements lead to this formula by an independent conclusive proof. 

One notices that the data from the oxidation of melezitose by per-iodic acid confirm the pyranose structure of the D-glucose unit in turanose, and therefore also in the case of maltose, in agreement with the original assignments for both of these disaccharides from methylation studies.
