Abstract:This paper compared the adsorption effects on lipid of Chito-oligosaccharides among different molecular weights in vitro.The result showed that all the Chito-oligosaccharides of different molecular weights had good adsorption on different kinds of lipids.During which,The adsorption of Chito-oligosaccharides with MW=5kDa~10kDa on lipin,bile salts and cholesterol were upmost.With a concentration of 300 mg of Chito-oligosaccharides,the rate of adsorption on lipin achieved to 5.26%,and the counterpart on sodium deoxycholate and sodium taurocholate arrived at 90.00% and 71.05% respectively,while the absorption rate of Chito-oligosaccharides with a concentration of 100 mg on cholesterol was 87.48%.Secondly,the adsorption of Chito-oligosaccharides with MW=2kDa~5kDal was better.And the adsorption of Chito-oligosaccharides with MW=200Da~2kDal was worst.Therefore,it could be inferred that there was a certain relationship between the lipid adsorption of Chito-oligosaccharides and their molecular weights.The greater molecular weight,the better lipid adsorption,in the range of MW10kDa.
Keywords:Chito-oligosaccharides  in vitro  lipid-adsorption
