摘要：

The structure of the polysaccharide glucoarabinogalactan, which is a branched polysaccharide, was established by chemical and spectral methods. Its main chain consists of alpha-1-->6-bound galactopyranose units. Galactopyranose atoms C-2 and C-3 act as branching points. The side chains contain galactopyranose, glucopyranose, and chains of beta-(1-->3)-bound arabinopyranose units. The linear structures of three galactooligosaccharides were identified and proved by partial acid hydrolysis.
