Which water-soluble vitamin serves as a coenzyme?

Vitamin B, which actually refers to a complex of several B vitamins, plays a vital role as a coenzyme in various biochemical reactions within the body. The B vitamins, such as B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin), are essential for energy production, the synthesis of neurotransmitters, and the metabolism of macronutrients.

Each B vitamin often acts as a coenzyme or is a precursor to coenzymes that facilitate important enzymatic reactions in metabolism, such as the conversion of carbohydrates, fats, and proteins into energy. This is crucial for maintaining normal physiological functions and overall health.

In contrast, while Vitamin C is also a water-soluble vitamin and plays important roles in antioxidant protection and collagen synthesis, it does not function as a coenzyme in metabolic pathways like the B vitamins do. Vitamins A and D are fat-soluble vitamins and have different roles in the body, such as vision, immune function, and calcium regulation, but they do not serve as coenzymes in the same capacity as
