Glycogen

Definition

Glycogen is a form of stored glucose in the body, mainly found in the liver and muscles, used for energy when needed.

Scientific / Technical Definition

Glycogen is a multi-branched polysaccharide of glucose that serves as a form of energy storage in animals and fungi. It is the primary carbohydrate storage form in the body, predominantly within the liver and skeletal muscles, functioning as a readily mobilized energy reserve.

Benefits

• Provides a quick source of energy during physical activity.
• Helps maintain blood sugar levels between meals.
• Supports endurance and high-intensity exercise performance.

Examples

• Stored in liver and muscle tissues
• Utilized during exercise

Additional Information

• Importance: Glycogen plays a crucial role in energy metabolism, particularly during periods of fasting and extended physical activity. It is essential for athletes for sustained energy release.
