Webglycogen phosphorylase degrades linear glycogen in which the glucose units are linked by α 1,4 glycosidic bonds, to within 4 glucose units of an α 1,6 glycosidic branch, at which … WebFig. 2 - 1,4- and 1,6-glycosidic bonds in polysaccharide glycogen. ... On the other hand, 1,6-glycosidic bonds form when the polysaccharide structure starts to branch. They form between the 1st carbon atom of one and the 6th carbon atom of another monosaccharide. In case you missed this, go back to figure 2 and observe the placement of the bonds.

Lactose Intolerance residues are left before the alpha-1,6 branch. Further breakdown proceeds with the debranching enzyme (with a transferase …
WebIn glycogen, glucose molecules are attached one after the other by alpha-1,4 linkages. However, in order to make glycogen more compact for storage, branch points are created to created links between many shorter glucose polysaccharides. These branch points connect glucose molecules by alpha-1,6 linkages. WebGlycogen phosphorylase will only act on non-reducing ends of a glycogen chain that are at least 5 glucoses away from a branch point. A second enzyme, Glycogen Debranching Enzyme (GDE), is therefore needed to convert alpha(1-6) branches to alpha(1-4) ...
