1H and 13C NMR chemical shifts are reported for several rhamnobioses and their acetylated derivatives. The effect of substitution on the rhamnose unit has been determined with respect to the anomeric carbons and linked carbons. These effects have bee

After repeated and vigorous treatments, a fully methylated glucan was obtained. Hydrolysis of the methylated glucan with sulphuric acid gave tetra-, tri-, di-, and mono-O-methyl-D-glucoses in a 5:5:3:1 ratio. Both the furanose and pyranose tetramethy
