Which vitamin is crucial for the metabolism of carbohydrates and fats?

Vitamin B is essential for the metabolism of carbohydrates and fats because it encompasses a group of water-soluble vitamins, including B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin). These vitamins play critical roles in various metabolic processes, particularly in converting macronutrients into energy.

For carbohydrates, B vitamins such as thiamine, riboflavin, and niacin are vital in glycolysis and the Krebs cycle (citric acid cycle), processes that break down glucose and other sugars to produce energy. Similarly, B vitamins are integral in fatty acid oxidation, where they help in breaking down fats for energy. Additionally, the B-vitamin complex aids in the synthesis of red blood cells and the maintenance of healthy nerve function.

The other vitamins listed do not have the same central role in carbohydrate and fat metabolism. Vitamin C primarily acts as an antioxidant and is involved in collagen synthesis. Vitamin A is important for vision and immune function. Vitamin D is crucial for bone health and calcium metabolism but does not play a direct role in the
