This work obtained the complexes of three fucoidan oligosaccharides with different molecular weights F1 （〉5 000）, F2 （1 000-5 000） and F3 （〈 1 000） by hydrolyzing Oligosaccharide collagen with sulfuric acid. It is found that the fucoidan oligosaccharide F3 can form complex with more Ce^IV than F1 and F2. Hydrolyzing collagen with the complex was carried out to produce amino acid and peptides. All the three fucoidan oligosaccharide complexes with CeIV（ F1, F2, F3） can catalyze by the artificial hydrolytic enzyme, and the activity of the complex of F3 is the highest.展开更多
