    The two types of glycosidic bonds (alpha-1,4 and alpha-1,6) in glycogen are shown. Many organisms store energy in the form of polysaccharides, commonly homopolymers of glucose. Glycogen, the polysaccharide used by animals to store energy, is composed of alpha-1,4-glycosidic bonds with branched alpha-1,6 bonds present at about every tenth monomer.

    Glycosidic bond - Wikipedia

    An α-glycosidic bond is formed when both carbons have the same stereochemistry, whereas a β-glycosidic bond occurs when the two carbons have different stereochemistry. One complicating issue is that the alpha and beta conformations were originally defined based on the relative orientation of the major constituents in a Haworth projection.

    Phosphorylase can only cleave α-1,4- glycosidic bond between adjacent glucose molecules in glycogen but branches exist as α-1,6 linkages. When phosphorylase reaches four residues from a branching point it stops cleaving; because 1 in 10 residues is branched, cleavage by phosphorylase alone would not be sufficient in mobilizing glycogen stores.
