The Structure of Chitin-Glucan Complex Isolated from Yeast Bud Scars

Abstract

The crude chitin-glucan complex isolated from yeast bud scars by the method of Bacon et al. was alternately treated with dilute alkali and acid to separate chitin and glucans. The respective content of chitin and glucan in the residual chitin preparation from the exhaustive chemical treatments was 83 % and 17 % by IR spectroscopy. The portion of glucans in the bud scars was constructed with (1-3)-β-D-/(1-6)-β-D-glucans. A possible construction model for the yeast scar ring is discussed.
