چکیده انگلیسی
Alginates comprised of essentially alternating units of mannuronic (M) acid-guluronic (G) acid (MG-alginate), and G-blocks isolated from a seaweed where subjected to partial acid hydrolysis at pH 3.5 The chain-length distribution of oligosaccharides in the hydrolysate were investigated by statistical analysis after their separation with high-performance anion-exchange chromatography and pulsed amperometric detection (HPAEC-PAD). Simulated depolymerisation of the MG-alginate provided an estimate of the ratio between two acid hydrolysis rate constants (p = 8.3 ± 1) and the average distribution of the MM linkages in the original sample of polysaccharide chains. In conclusion, we found HPAEC-PAD together with statistical analysis was a useful method to investigate the fine structure and some properties of binary polysaccharides.
