| Abstract: | The structure of the branched polysaccharide glucoarabinogalactan was investigated by periodate oxidation, methylation, and 13C NMR spectroscopy. The main chain consists of  -1 6-bonded galactopyranoses. 12-Bonded D-glucopyranoses and 13-bonded D-galactopyranoses are located on the unreducing ends. There is a short side chain with  -13-bonded L-arabinopyranoses. |
