Isolation of the galactan ofPhyllophora nervosa and characterization of its structure
1. The chemical composition of the galactan of the Black-Sea algaPhyllophora nervosa has been established and its structure has been studied. The polysaccharide is linear and is constructed of D-galactose residued connected by 1 → 3 glycosidic bonds and of 3,6-anhydro-D-galactose residues connected by 1 → 4 bonds:-(4-0-β-D-Galp-1→3-α-D-3,6-AhGalp-1)-.
2. The ester nature of the bond of the sulfuric acid residues with the primary and secondary carbon atoms of the galactose residues has been shown.
