Conversion of yeast mannan polysaccharide in mannose oligosaccharides with a thiopropargyl linker at the pseudo-reducing end

- Commercial mannan from Saccharomyces cerevisiae.
- Selective breakage of 1→6 linkages through acetolysis.
- Conversion of peracetylated oligomannooligosaccharide in propargylthioglycosides.
- Optimization of the separation conditions of the deacetylated derivatives.
