What is Polysaccharides of Algae. XXXVII. Characterization of Hybrid Structure of Substituted Agarose from Polysiphonia morrowii (Rhodophyta, Rhodomelaceae) Using β-Agarase and 13C-NMR Spectroscopy about?
Structure of gel-förming galactan from Polysiphonia morrowii was analysed using bacterial ß-agarase and 13 C-nucIear magnetic resonance ( 13 C-NMR) Spectroscopy. The polysaccharide was shown to contain: a) blocks composed of agarobiose residues, partly 6-O-methylated and 6-sulfated, which are sensitive to enzymolysis; b) extended blocks composed of agarobiose 6-suIfate residues, which are resistant to ß-agarase action. The latter blocks contain also ß-D-galactopyranosyl-(l -\*4)-a-L-galactopyranose 6,6'-disulfate residues (biogenetic precursors of agarobiose 6-sulfate), which are hardly detectable by "C-NMR spectrum of the starting polysaccharide. Action of alkali on the enzyme-resistant fractibn afforded a polysaccharide preparation having 13 C-NMR spectrum of agarose 6-sulfate.
