Abstract:

The water-soluble polysaccharides from Chaetangium fastigiatum were fractionated with cetrimide. The complexed material was subjected to fractional solubilization in solutions of increasing sodium chloride concentration and seven fractions were separated and analyzed. Two of the fractions were subjected to methylation and desulfation-methylation analyses. The results indicate that this seaweed contains a system of sulfated polysaccharides consisting in part of a galactan and an α-d-(1 → 3)-linked mannan, 2- and 6-sulfated, and having single stubs of β-(1 → 2)-linked d-xylose. Composition dispersity of the mannan is produced by variation of the amount and disposition of the sulfate groups and of the content of the xylose side-chains. © 1987.
