Determination, by methylation analysis, of the glycosyl-linkage compositions of microgram quantities of complex carbohydrates

A methylation-analysis procedure has been developed by which the glycosyl-linkage compositions of microgram quantities of complex carbohydrates, including those containing hexosyluronic acid residues, can be determined. The effectiveness...

The structure of the Aerobacter aerogenes A3(S1) polysaccharide. I. A reexamination using improved procedures for methylation analysis.

The acidic slime polysaccharide from Aerobacter aerogenes, A3(Sl), has been converted in three reaction steps to a fully methylated, neutral polysaccharide. The permethylation reaction of Hakamori (Hakamori, S., 1964, J. Biochem. (Tokyo)...

Antitumour Polysaccharide derived Chemically from Natural Glucan (Pachyman)

WE have reported1 that the polysaccharide lentinan obtained from Lentinus edodes (Berk.) Sing. (a popular edible mushroom in Japan) had a strong antitumour activity against sarcoma 180 implanted subcutaneously in mice, and that almost co...

13C chemical shifts of solid (1-4)-α-D-glucans by cross polarization/magic angle spinning (CP/MAS) NMR spectroscopy. Conformation-dependent 13C chemical shift as a reference in determining conformation in aqueous solution

13C chemical shifts of linear and cyclic amyloses in solid state were measured by cross polarization/magic angle spinning (CP/MAS) NMR spectroscopy. It is found that rapid conformational isomerism occurs in aqueous solution for amylose a...

HIGH RESOLUTION 13C NMR STUDY OF (1→3)-β-D-GLUCANS BY CROSS POLARIZATION/MAGIC ANGLE SPINNING: EVIDENCE OF CONFORMATIONAL HETEROGENEITY

Conformation of various (1→3)-β-D-glucans in solid state was examined by 13C cross polarization/magic angle spinning NMR spectroscopy. It was found that high molecular-weight glucans adopt mainly helix form, whereas low molecular weigh...
