What is the approximate amount of water stored with one gram of glycogen?

Glycogen is a form of stored carbohydrate found in the liver and muscle tissues, and it plays a critical role in energy metabolism during physical activities. When glycogen is stored in the body, it is associated with a significant amount of water. On average, the storage of one gram of glycogen is accompanied by approximately three grams of water. This relationship exists because glycogen is highly hydrophilic, meaning it attracts and holds water molecules.

The correct answer reflects the physiological process of glycogen storage and hydration. This association between glycogen and water is important for athletes and individuals looking to optimize their performance, as adequate glycogen stores contribute to energy availability, while the water retained helps maintain hydration status. Understanding this relationship can help in planning nutritional strategies and optimizing performance for endurance events and high-intensity training.
