Question

Which of the following vitamins is fat-soluble?
A. A, B, C, K.
B. A, B, D, E.
C. A, D, E, K.
D. A, D, C, K.

Answer 1

Hint:Vitamin A, D, E, K are fat-soluble vitamins and they are not loose easily from the body, like water-soluble vitamins such as vitamin C and members of the vitamin B complex. Vitamins are necessary molecules required to operate certain metabolic functions in the body.

Complete answer:
Vitamins are an essential organic molecule that acts as a micronutrient in the body. They are required in a trace amount to catalytic in certain reactions and utilise in the body in various metabolic activity. The number of vitamins is present and 13 known vitamins are required which are categorised into water-soluble and fat-soluble. Deficiency of any vitamin can cause deficiency disease or disorder in the body to inhibit the generation of such disease. We require an optimum amount of vitamins. Fruits and vegetables are good sources of vitamins. Some vitamins are formed inside the body such as vitamin D in the presence of sunlight and some have come from foods.
Fats soluble vitamins such as Vitamin A, D, E, K are stored in fatty tissue called adipose tissue of the body and not easily lost from the body as compared to water-soluble vitamin-like C and B complexes. Water-soluble vitamins excreted out from the body via urine.
Vitamin A called retinol and deficiency cause night-blindness and keratomalacia.
Vitamin D is called cholecalciferol and deficiency causes rickets and osteomalacia.
Vitamin E is called tocopherol and deficiency causes hemolytic anemia in young ones.
Vitamin K is called phylloquinone and deficiency cause bleeding diathesis
Vitamin C is called ascorbic acid and deficiency causes megaloblastic anemia.
Vitamin B ( Thiamin), B2 (Riboflavin), B3 (Niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (Biotin), B9 (Folic acid) B12 (Cyanocobalamin) and deficiency cause beriberi, ariboflavinosis, pellagra, paresthesia, anaemia, dermatitis, birth defect during pregnancy, megaloblastic anaemia respectively.
Hence, the correct option is C.

Note: Vitamins play vital and multiple roles in the body and require certain metabolic enzymatic reactions to catalyze the reaction. They play an important role in fetal growth and development and health maintenance in adults, its deficiency can cause weakening of immunity.
