Preparation of a sulfated linear (1→4)-β-d-galactan with variable degrees of sulfation

Vogl, H. ; Paper, D. H. ; Franz, Gerhard


A linear 1,4-β-d-galactan has been prepared by partial acid hydrolysis of the major lupin seed polysaccharide on a preparative scale. The galactan has been characterized by acetylation and methylation analysis, by GPC, as well as by its 1H- and 13C-NMR-spectra. Sulfation with increasing amounts of SO3-pyridine yielded a series of galactan sulfates with increasing DS. In all derivatives, the ...
