Which of the following vitamins is considered water-soluble?

1. Vitamin A

2. Pantothenic acid

3. Vitamin D

4. Vitamin E

The correct answer is: Pantothenic acid

Pantothenic acid is classified as a water-soluble vitamin, which is important for various physiological processes in the body. Water-soluble vitamins, including the B vitamins and vitamin C, dissolve in water and are typically not stored in large quantities within the body. Instead, they must be consumed regularly through diet because excess amounts are excreted in urine. Pantothenic acid specifically plays a critical role in the synthesis of coenzyme A, which is involved in the metabolism of carbohydrates, fats, and proteins. Additionally, it contributes to the production of red blood cells and hormones, highlighting its importance in energy metabolism and overall health. In contrast, the other options—Vitamin A, Vitamin D, and Vitamin E—are fat-soluble vitamins. These vitamins are stored in the body's fatty tissues and liver, and they require fat for proper absorption. Each of these vitamins has distinct functions, such as vision and immune function for vitamin A, calcium metabolism for vitamin D, and antioxidant properties for vitamin E. However, due to their classification as fat-soluble, they do not fit the criterion of being water-soluble like pantothenic acid does.
