The role of vitamins in metabolism is multifaceted, as they act as essential coenzymes and cofactors in numerous biochemical reactions. These organic compounds facilitate critical processes such as energy production, metabolism of macronutrients, and synthesis of hormones and neurotransmitters. Vitamins are not synthesized in adequate amounts by the body, necessitating their acquisition through diet. A deficiency in any specific vitamin can lead to metabolic disruptions and various health issues. Understanding the roles of different vitamins is vital for ensuring proper nutritional intake and maintaining overall health.
