A polysaccharide of unknown structure was isolated, subjected to exhaustive methylation, and acid hydrolysed. Analysis of the products revealed three methylated sugars: 2,3,4-tri-O-methyl-D-glucose, 2,4-di-O-methyl-D-glucose and 2,3,4,6-tetra-O-methyl-D-glucose in the ratio 20:1:1, What glycosidic bonds must be present in this polysaccharide? What is the structure of the polysaccharide? Draw a repeating structure of the polysaccharide, showing glycosidic linkages and branches.
