Complexes of Carbohydrates with Metal Cations. XI. Paper Electrophoresis of Polyols in Solutions of Calcium Ions

Paper electrophoresis in an electrolyte containing calcium ions is a method suitable for the separation and characterization of many polyhydroxy compounds. The method is based on the formation ofcomplexes between the cation and at least two hydroxyl groups of the compounds. Electrophoretic mobilities are listed for many sugars, methyl glycosides and cyclitols. The mobilities convey someinformation on the structure of the compounds. The correlation of electrophoretic mobilities with the configuration and conformation of the compounds is discussed.
