Where it appears

Open metabolism map
1

Phosphorolysis of glycogen

Glycogen phosphorylase releases glucose 1-phosphate from non-reducing chain ends.

Glycogen metabolism · irreversible
2

Branch-point removal

The debranching enzyme rearranges short chains and hydrolyzes alpha-1,6-linked glucose.

Glycogen metabolism · irreversible
5

Glycogen-chain initiation

Glycogen synthase transfers glucose from UDP-glucose onto a primer chain.

6

Alpha-1,4 chain extension

Glycogen synthase extends existing chains with alpha-1,4-linked glucose residues.

7

Branch formation

Branching enzyme creates alpha-1,6 linkages and new non-reducing ends.
