Carbohydrates and their Metabolism (Part 2)

Carbohydrates are mainly used as fuel, either in a direct manner, after storage as glycogen, or after conversion to lipids.


  • Gluconeogenesis, the pathway for synthesis of new glucose and one of the major functions of the liver, is inhibited during this time.
  • Glycogen is the storage form of glucose mainly found in liver and muscle.
    Glycogen stores are regulated by a balance between glycogen synthesis (glycogenesis) and breakdown (glycogenolysis).
