Polysaccharides, acetolysis structure

Various techniques have been utilized for sequencing the glycosyl residues of polysaccharides and oligosaccharides. These techniques are elaborations of the commonplace procedure of converting polysaccharides, by partial hydrolysis, into structurally analyzable oligosaccharides. This conversion is generally achieved by partial hydrolysis with acid, by acetolysis,131 or by formolysis.62 These reagents may differ in the... [Pg.276]

Ballou and coworkers - studied in greater detail the structure of yeast mannan produced by S. cerevisiae grown in a culture medium containing D-glucose. They showed that controlled acetolysis by the method of Gorin and Berlin selectively cleaves (1 — 6)-linkages of this polysaccharide, and mainly produces (in excellent yield) di-, tri-, and tetra-saccharides having relatively stable (1 2)- and (1 - 3)-... [Pg.394]
