Which of the following is classified as fat soluble?
- A- Vitamin d.
- B- Niacin.
- C- Ascorbic acid.
- D- Thiamine hydrochloride.
- E- Riboflavin.
The answer is: A. Vitamin D
Here's why:
- Fat-soluble vitamins:
These vitamins dissolve in fat and can be stored in the body's fatty tissue. Examples include vitamins A, D, E, and K.
- Vitamin D:
This vitamin plays a crucial role in bone health, immune function, and cell growth. It is primarily obtained from sunlight exposure and some foods like fatty fish and eggs.
- Niacin (B3):
A water-soluble vitamin involved in energy metabolism and nervous system function.
- Ascorbic acid (vitamin C):
Another water-soluble vitamin important for antioxidant function and collagen synthesis.
- Thiamine hydrochloride (vitamin B1):
A water-soluble vitamin essential for energy metabolism and nervous system function.
- Riboflavin (vitamin B2):
A water-soluble vitamin involved in energy metabolism and vision.
Therefore, only Vitamin D among the listed options is fat-soluble. The others are all water-soluble vitamins that dissolve readily in water and cannot be stored in the body in significant amounts.
