Complexes of Carbohydrates with Metal Cations. XIV. Separation of Sugars and Alditols by Means of Their Lanthanum Complexes

Abstract

The mobilities of numerous polyols, sugars and methyl glycosides on ion-exchange resin thin-layer plates in the calcium and lanthanum form have been measured. Under these conditions, alditols which have a threo-threo sequence of hydroxy groups complex more strongly with lanthanum than with calcium, whereas methyl glycosides complex less strongly.
