Using different degradation methods (acid degradation, enzyme degradation, oxidative degradation) to degrade algin, a series of algin oligosaccharides with polymerization degree below 20 can be obtained. It is a linear low polymer composed of β-D-polymanuronic acid (M) and α-L-polygururonic acid (G). There are three types of products: polymanuronic acid (PM), polygururonic acid (PG) and heterozygous alginosaccharide (PMG).
