Chitooligomer

WebChitooligosaccharide (COS, Figure 1c), also called chitosan oligomer or chitooligomer, is defined as chitosan with a degree of polymerization Â20 and an average molecular weight of less than 3900 Da (generally 0.2 3.0 kDa) [12,13]. Sometimes much larger molecules are also called COS, and there Webhydrogen bondings of chitooligomer chains would assemble the ligands and provide unique glycoside clustering effects, which are required for cell culture engineering. Herein, we showed the influences of carbohydrate-functionalized surface geometries on the alignment and proliferation of C2C12 myoblast cells.
