A. Albrecht et U. Rau, ACETYLATION OF A BETA-1,6-BRANCHED BETA-1,3-GLUCAN, YIELDING SCHIZOPHYLLAN-ACETATE, Carbohydrate polymers, 24(3), 1994, pp. 193-197
Several enzymatic and chemical methods were employed to attempt to acy
late the homoglucan Schizophyllan. The enzymatic attempts with an immo
bilized lipase and a protease failed because of the lack of a suitable
organic solvent and for steric reasons. Of the chemical methods attem
pted, only strong add catalysis with a large excess of a carboxyl comp
ound led to acetylation. The degree of acetylation is discussed.
