Mechanochemical phosphorylation and solubilisation of β-D-glucan from yeast Saccharomyces cerevisiae and its biological activities.
To obtain a water-soluble β-D-glucan derivative cleanly and conveniently, a highly efficient mechanochemical method, planetary ball milling, was used to phosphorylate β-D-glucan isolated from yeast Saccharomyces cerevisiae in solid state. Soluble β-D-glucan phosphate (GP) with a high degree of subst...
