2. Glycogen Metabolism
Introduction, Structure and Glycogenolysis Pathway

3. INTRODUCTION
0 Glycogen is a branched polymer of α-D-glucose.
0 Glycogen is stored in liver and muscle.
0 although most other cells store small amounts of
glycogen for their own use.
0 Glycogen is serve as reserved fuel for the body.
0 Liver glycogen maintains glucose level in blood.

4. Structure of Glycogen

5. GLYCOGEN METABOLISM
(GLYCOGENOLYSIS)
--Occurs when body needs maintain blood glucose level.

6. Glycogenolysis
0 Glycogen phosphorylase
0 Debranching enzyme
(Transferase activity)
0 Action of phosphorylase
0 Phosphoglucomutase
0 Glucose-6-phosphatase
-Every step carried forward by
utilizing different enzymes
