STUDIES ON THE WATER-SOLUBLE POLYSACCHARIDE OF Ulva Pertusa

The physical and chemical property of the water-soluble polysaccharide from Ulva pertusa was analyzed. 13C-NMR spectrum was used to determine the chemical structure of the polysaccharide, and it revealed that the polysaccharide was mainly composed of major repeatedly structural units: [β-D-GlcpA-(1→4)-α-L-Rhap3S]m and [α-L-IdopA-(1→4)-α-L-Rhap3S]
