Starch, glycogen and cellulose are made up of repeating monomeric units of glucose with the number of glucose units and the different linkage types different these molecules. E.g the linkage between glucose units in glycogen is alpha 1-4 linkages and in cellulose, we have glucose in beta 1-4 linkages.
In chitin, a derivative of glucose is present in repeating units, here, we have N-acetyl-D-glucosamine in beta 1-4 linkages.
