Many vitamins act as essential coenzymes, facilitating enzymatic reactions vital for metabolism.
Examples
- Niacin (B3): Precursor for NAD+, vital for Krebs cycle.
- Riboflavin (B2): Precursor for FAD, vital for electron transport.
- Thiamine (B1): Critical for carbohydrate metabolism.
Clinical Deficiency
