Which vitamin is known as riboflavin and is essential for energy metabolism of fats, proteins, and carbohydrates?

Riboflavin is indeed known as Vitamin B2, and it plays a crucial role in energy metabolism. This vitamin is involved in various metabolic processes, including the conversion of carbohydrates, fats, and proteins into energy. It acts as a precursor for coenzymes, such as FMN (flavin mononucleotide) and FAD (flavin adenine dinucleotide), which are essential for the metabolism of macronutrients. These coenzymes are vital in the processes of oxidation-reduction reactions that occur during the metabolism of food, facilitating the release of energy that the body can use.

The other vitamins mentioned do not share the same specific functions as riboflavin. Vitamin B1, also known as thiamine, is primarily involved in carbohydrate metabolism and supports nerve and muscle function. Vitamin B3, or niacin, is more directly linked to the metabolism of carbohydrates and fats but is not associated with riboflavin's role in energy production. Vitamin B5, known as pantothenic acid, is essential for synthesizing coenzyme A, which is important for fatty acid metabolism but does not cover the full spectrum of functions that riboflavin provides.

In summary, riboflavin's essential role
