Abstract: The effect of type of glycosidic linkage on CD spectra in a series of aldobiouronic and pseudoaldobiouronic acid derivs. was studied. The spectra reflect the presence of D-glucuronic and D-galacturonic acid in the mols. of studied substances, as well as solvent effects. Characteristic regularities in the intensity of Cotton effects were found for the series of pairs of α- and β-linked xylan type aldooligouronic acid derivs. In addn., CD spectra of pseudoaldobiouronic acid derivs. differ depending upon the positional isomerism.
