Carbohydrates-Simple sugars are sent to the liver where they are converted to glucose. The glucose then travels to the blood or is converted to glycogen and fat (triglyceride). The glycogen and fat will be stored in the liver and adipose tissue, respectively, as reserves for the post-absorptive state.
In humans, glycogen is stored and produced by the hepatocytes in the liver. The main function of glycogen is as a secondary long-term energy-storage molecule. The primary energy-storage molecules are adipose cells. Glycogen is also stored in muscle cells. Muscle glycogen is converted into glucose by the muscle cells whenever muscles are overworked and tired.
