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. Webb1 sep. 2024 · After the initial autoglucosylation of a glycogenin dimer, glycogen synthase (GS) is able to attach new d-glucose units using the substrate UDP-glucose.Once the chain reaches a specific length, glycogen branching enzyme (GBE) cleaves a portion of the chain and reattaches it via an α-(1 6) linkage, creating a new branch point.
