Here are some facts about glycogenesis:
Definition
Glycogenesis is the process of converting glucose into glycogen for storage in the body.
Location
Glycogenesis occurs in the liver cells, also known as hepatocytes.
Stimulation
Glycogenesis is stimulated by glucagon when the body is resting and by insulin when blood glucose levels are high.
Purpose
Glycogen is a storage molecule for glucose that the body can use for energy when blood glucose levels are low.
Process
During glycogenesis, glucose is joined to a core of glycogen via α-1,4 linkage.
Intermediary
The molecule uridine-5'-diphosphate (UDP)-glucose is a key intermediary in glycogenesis.
Storage
The liver stores glycogen to stabilize blood sugar levels and provide energy for other tissues. Skeletal muscle cells also store glycogen, but the total amount of glycogen stored in the body is mostly in the muscle cells.
Glycogenolysis
When the body needs energy, it breaks down stored glycogen back into glucose in a process called glycogenolysis.
