Question

Which of the following is not a fat-soluble vitamin?
(A) Vitamin A
(B) Vitamin B complex
(C) Vitamin D
(D) Vitamin E

Answer 1

Fat-soluble vitamins are those which are soluble in organic solvents and are absorbed along with fats in our diet and it can be stored in our body’s fatty tissue. They are derived from food and dietary supplements. Vitamins are divided into various classes such as fat-soluble based on their physical and chemical properties.

Complete step by step answer:
We know that fat-soluble vitamins are present in food containing fats and are not dissolved in water. This classification is done based on solubility. Therefore in the given question A, D, E are such class of vitamins which come under the category of fat-soluble vitamins.
These fat-soluble vitamins are similar to oil and are not soluble in water. They are soluble in organic solvents.
Also, the vitamin B complex consists of all water-soluble vitamins except vitamin C. These include thiamine, riboflavin, niacin, pantothenic acid, pyridoxine, biotin, folic acid, and cobalamins.
Therefore vitamin A, D, E are fat-soluble and vitamin B is water-soluble.

So, the correct answer is Option B .

Note: Vitamins are essential micronutrients needed by our bodies in a small amount to support a range of vital functions. They play an important role in the various physiological processes such as vision, bone health, immune function, and coagulation. Also, excessive doses of vitamin A, D, E, K can lead to various health problems.

Fat-soluble vitamins are not lost when food containing them are cooked. They are soluble in lipids(fats). Also, they are not needed by our body every day thus they are stored in liver and adipose(fat) tissue when not used.
