Abstract: | The neutral component of d-mannan of bakers' yeast (Saccharomyces cerevisiae), consisting solely of d-mannose residues, was precipitated with concanavalin A to give four fractions. The first three displayed similar reactivities in quantitative precipitin reaction against concanavalin A and homologous anti-S. cerevisiae serum, but the fourth showed different precipitin curves. Analysis of the fractions by acetolysis indicated structural differences. The different behavior of the last fraction in precipitin reactions could be due to a lower content of branching points, or to shorter chain-lengths. |
