Abstract Chemical and spectroscopic methods showed that the water-soluble polysaccharide extracted fromSchizymenia dubyi from Sicily was composed of 1/0.75/1.3 galactose, glucuronic acids and sulfate groups; 45% of total galactose was present as the L-form and no 3,6-anhydrogalactose was detected. The structural characteristics of this galactan of molecular weight 290 000 were close to sulfated polysaccharide with 1,3-, 1,4- and terminal-linked galactose units and secondary ramifications in 1,3,6; 1,4,6; 1,3,4 and 1,6. Permethylation analysis suggested the presence of sulfate groups on positions O-2 and/or O-3 of 1,4-linked galactose and on O-2 and/or O-4 of 1,3-linked residues.
