Question

Which of the following is a fat-soluble vitamin and its related deficiency disease?
A) Retinol: Xerophthalmia
B) Cobalamin: Beri beri
C) Calciferol: Pellagra
D) Ascorbic: scurvy

Answer 1

Hint:Fat soluble vitamins are those vitamins that are absorbed with fats in the diet and can be stored in the body's fat tissue. They are absorbed in lymph and are transported in the blood with carrier proteins. As these can be stored in our body, its excessive accumulation can be toxic.

Complete answer:
>Retinol is derived from Vitamin A , which is a fat soluble vitamin because they can dissolve in organic solvents and are absorbed and transferred just like fat in our body.
>The deficiency of retinol( Vitamin A causes eye disease. Its deficiency can dry out tear ducts and eyes which is called Xerophthalmia. It can develop into night blindness.
>Cobalamin is also called Vitamin B12 and is not fat soluble .It is important for the formation of red blood cells .Its deficiency can cause anemia and even permanent damage to the brain and nerve.
>BeriBeri is a disease caused due to Vitamin B1 deficiency. It affects the heart and circulatory system.
>Calciferol is Vitamin D2. Its deficiency can cause Rickets.
>Pellagra is caused due to lack of Niacin also called Vitamin B3.
>Ascorbic acid is a water soluble vitamin also called Vitamin C. It is a reducing and antioxidant agent and fights with bacterial infections.
>Deficiency of Ascorbic acid also called Vitamin C can cause scurvy.

Hence, the correct answer is option (A).

Note:Vitamins are important for our body .There are two types of vitamins : Water soluble and fat soluble. water soluble are easily dissolved in body fluids and hence we are unable to store them so we have to take them regularly. On the other hand, fat solubles are stored along with our fat.
