GLYCOGEN
Glycogen
Glycogen Usage
Glycogen Composition
❖ ‘Animal Starch’
❖ Branched polymer of glucose
❖ Main chain- α(1→4) linkage
❖ Side chain- α(1→6) linkage
Glycogen Structure
❖ Helical Structure
❖ 12-14 glucose/chain
❖ Branch occurs every 8-12 glucoses
❖ 3D branching structure
❖ Up to 120,000 glucose per glycogen molecule
❖ ~10-40nm diameter
Glycogen Storage
❖ Glycogen granules- =20-40 molecules
❖ Up to 10% of liver mass
❖ 1-2% of muscle
