| Popis: | Reactivity of the glycosidic bonds in oat β-glucan in homogeneous acid catalyzed hydrolysis in aqueous solution was found to depend on their position in the polysaccharide chain. The bonds near the chain ends have lower hydrolytic stability in presence of HCl than the bonds in the middle. Reaction kinetics was monitored by measuring the molar mass distribution (DP ~ 30…3500) and formation of short oligosaccharides (DP |
