WebbAbstract. Glycogen is a strongly branched polymer of α-D-glucose, with glucose residues in the linear chains linked by 1→4-bonds (~93% of the total number of bonds) and with branching after every 4-8 residues formed by 1→6-glycosidic bonds (~7% of the total number of bonds). It is thought currently that a fully formed glycogen molecule (β ... WebbDue to the many monomers in a starch molecule, it takes longer to digest than glucose. Starch is constructed from two different polysaccharides: Amylose (10 - 30% of starch) Unbranched helix-shaped chain with 1,4 glycosidic bonds between α-glucose molecules. The helix shape enables it to be more compact and thus it is more resistant to digestion.
