The galactomannan system from the endosperm of the seed of Gleditsia triacanthos

The galactomannan system from the endosperm of the seed of Gleditsia triacanthos is composed of four water-soluble galactomannans having a narrow range of distribution of sugar compositions. Nevertheless, molecular-weight and possible chain-distribution heterodispersion were observed. All of the gal...

520 3 |a The galactomannan system from the endosperm of the seed of Gleditsia triacanthos is composed of four water-soluble galactomannans having a narrow range of distribution of sugar compositions. Nevertheless, molecular-weight and possible chain-distribution heterodispersion were observed. All of the galactomannan fractions obtained by fractional extraction and further stepwise precipitation with ethanol contained small proportions of xylose and arabinose, and their methylation analysis suggests that minor amounts of lateral chains are ended by arabinofuranose or xylopyranose residues. The variation of the rotations of the galactomannan fractions in solvents of increasing chaotropic power agrees with the suggestion that, in aqueous solution, these molecules exist in an extended, ribbon-like conformation. These entropically unfavorable conformations would be promoted by the spontaneous, noncovalent, and ordered binding of the molecules, producing lower free-energy aggregates; further interactions between these aggregates form gel networks that are maintained in solution by the galactose lateral chains. Methylation analysis shows that the galactomannans have the structure accepted for these polysaccharides. Only minor deviations from this structure were found, but even if they have minor importance as far as the primary structure of the polysaccharide is concerned, they could be important in determining the secondary and tertiary structures and, consequently, in the formation of aggregates and gel networks. © 1984.  |l eng
