Highly sulphated galactan from Halymenia durvillei (Halymeniales, Rhodophyta), a red seaweed of Madagascar marine coasts.
Int J Biol Macromol. 2009 Aug 01; 45(2):140-5.IJ

Abstract

Halymenia durvillei is a red seaweed with a great potential as sulphated galactan producer collected in the coastal waters of small island of Madagascar (Nosy-be in Indian Ocean). To elucidate the structure of its polysaccharide, NMR (1H and 13C), FTIR, HPAEC and different colorimetric methods were carried out. It has been shown that this polysaccharide, consisted mainly of galactose, was branched by xylose and galactose in minor amounts. Arabinose and fucose were also detected. This galactan was found highly sulphated (42%, w/w) and pyruvylated (1.8%, w/w). Analysis of glycosidic linkages by CPG-MS and 13C NMR indicated that the polysaccharide has the defining linear backbone of alternating 3-beta-D-galactopyranosyl units and 4-linked alpha-L/D-galactopyranosyl residues. 3,6-Anhydrogalactose units have been also detected in minor quantity. This lambda-carrageenan like polysaccharide has shown original sulphatation patterns with 2-O (26%) or 2/6-O (58%) sulphated 3-linked beta-D-galactopyranosyl units and 6-O (19%) or 2/6-O (47%) 4-linked alpha-L/D-galactopyranosyl residues.
