Water-soluble sulfated polysaccharides from the red seaweed Chaetangium fastigiatum. Analysis of the system and the structures of the α-d-(1 → 3)-linked mannans

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 subje...
