Describe how the maltose would be affected if the subcomponents were joined by 1–6 linkages instead. Predict how this might affect the function of the resulting molecule.

Respuesta :

The structure of amylose, which is made up of alpha glucose monomers joined by 1-4
linkages, is unbranched. If these bonds were
instead 1-6 linkages, the molecule would have a branched structure. This would result in a more easily digestible form of the molecule. Glycogen phosphorylase can only break terminal bonds, so with more branches, there will be more terminal glucose molecules, resulting in increased catalytic efficiency.

The maltose would be affected if the subcomponents were joined by 1–6 linkages instead - would be a more branched molecule with increased catalytic efficiency.

The structure of maltose

  • Maltose is composed of two units of D- glucose linked together through an alpha 1,4 glycosidic bond.
  • It is unbranched
  • If these bonds were instead 1-6 linkages, the molecule would have a branched structure.
  • This would result in a more easily digestible form of the molecule.
  • Glycogen phosphorylase can only break terminal bonds
  • As it has more branches so there will be more terminal glucose molecules, resulting in increased catalytic efficiency.

Thus, The maltose would be affected if the subcomponents were joined by 1–6 linkages instead - would be a more branched molecule with increased catalytic efficiency.
