Question

Which of the following is called vitamin H?
A.Biotin
B.Folic acid
C.Thiamine
D.Niacin

Answer 1

Hint: We can say vitamin is an organic molecule which is an important micronutrient that an organism wants in small quantities for the proper functioning of its metabolism. We can classify vitamins as either water-soluble or fat-soluble. In humans there are 13 vitamins present.

Complete step by step answer:
All the given vitamins (Biotin, Folic acid, Thiamine, Niacin) belong to the vitamin B family.
Biotin is a water-soluble vitamin which is a part of the vitamin B family. It is called vitamin H. Our body requires biotin to help convert certain nutrients into energy. It plays a vital role in the health of our hair, nails, and skin.
Therefore, Option (A) is correct.
Folic acid is the synthetic form of folate that is a naturally occurring B vitamin. Folate helps DNA and other genetic material. It is especially vital in prenatal health. Folate is known as vitamin B9, is a B vitamin which occurs naturally in some foods such as dried beans, peas, lentils, oranges, and whole-wheat products.
Therefore, Option (B) is incorrect.
Thiamine is also called vitamin B1, and it is one of eight important B vitamins, which has many important functions throughout the body. It’s used by all our cells and is useful for converting food into energy. Since the human body is unable to produce thiamine, it should be consumed through thiamine-rich foods like meat, nuts and whole grains.
Therefore, Option (C) is incorrect.
Niacin is called as nicotinic acid is an organic compound and a form of vitamin B3. It is an essential nutrient for humans. It is available in foods like yeast, meat, fish, milk, eggs, and cereal grain.
Therefore, Option (D) is incorrect.
Therefore, Option (A) is correct.


Note:
We must know that the fat-soluble vitamins are stored in the fatty tissue of the human body. Vitamins A, D, E, and K are the 4 fat-soluble vitamins present in the body. These vitamins are more readily absorbed by the body in the presence of dietary fat.
We also remember that there are 9 water-soluble vitamins. Any leftover water-soluble vitamins leave the body via urine. Though the body preserves a small reserve of these vitamins, they have to be taken on a consistent basis to prevent shortage in the body. Vitamin B12 is the only water-soluble vitamin, which can be stored in the liver for several years.
