Research paper thumbnail of Structural characterization of cold extracted fraction of soluble sulfated polysaccharide from red seaweed Gracilaria birdiae

The composition of the polysaccharide in wt% was determined as: b-D-galp (50.3%), 3,6-anhydro-a-L-galp (40.5%) and -a-L-galp-6 sulfate (9.2%). The ratio of L/D units (b-D-galp units and 3,6-anhydro-a-Lgalp + a-L-galp-6 sulfate) is that of an ideal agarose. The sulfate content calculated by S% accounts for 6.4%. 1D and 2D NMR techniques were employed in order to assign the spin system of polysaccharide without partial degradation. The structure is composed of fi 4-3,6anhydro-a-L-galp (1 fi 3)b-D-galp 1 fi segments, with the possibility of a a-L-galp unit substituted at the 6-position by sulfate ester.
