| Abstract: | The sea urchin contents sulfated polysaccharide XB-3 was desulfurizated to be XB-3D.XB-3 and XB-3D for methylation,right before and after desulfurization carried out partially methylated sugars by gas chromatography-mass spectrometry,and XB-3 and XB-3D structural information was obtained,including its main chain and branched-chain composition,connection,sulfuric acid-substituted position and structure model. |
