Suppose that a polymer of glucose with alternating \(\alpha(1 \rightarrow 4)\) and \(\beta(1 \rightarrow 4)\) glycosidic linkages has just been discovered. Draw a Haworth projection for a repeating tetramer (two repeating dimers) of such a polysaccharide. Would you expect this polymer to have primari
