Which of the following is NOT a function of vitamin C?

Vitamin C, also known as ascorbic acid, plays several important roles in the body, but the storage of energy as glycogen is not one of its functions. Glycogen is a form of energy storage in the body, primarily found in the liver and muscles, and its storage and mobilization are largely facilitated by other substances, such as carbohydrates and specific enzymes.

In contrast, vitamin C is vital for the synthesis of collagen, which is essential for the structural integrity of skin, cartilage, and bones. It is also well-known for its antioxidant properties, helping to protect cells from oxidative stress by neutralizing free radicals. Additionally, vitamin C aids in several other biochemical processes, but it is not directly involved in energy storage as glycogen.

Understanding these distinctions highlights the specific functions of vitamins and their roles in human health, emphasizing that while vitamin C is critical for many physiological processes, energy storage is managed through other biological mechanisms.
