Question

Name the vitamin that is not present in milk.

Answer 1

Hint: Vitamins have many roles in the body, including metabolism cofactors, oxygen transport and antioxidants. They help the body use carbohydrates, protein, and fat. Milk contains the water-soluble vitamins thiamine (vitamin $\mathop B\nolimits_1 $), riboflavin (vitamin $\mathop B\nolimits_2 $), niacin (vitamin $\mathop B\nolimits_3 $), pantothenic acid (vitamin $\mathop B\nolimits_5 $), vitamin $\mathop B\nolimits_6 $ (pyridoxine), vitamin $\mathop B\nolimits_{12} $ (cobalamin).

Complete answer:
The vitamin that is not present in milk is Vitamin C . Vitamin C is also known as ascorbic acid (AA) or ascorbate. In many multicellular organisms, it acts as an essential nutrient that is required for the repair of worn-out tissues, and enzyme-based synthesis of neurotransmitters.
It is an essential dietary supplement. It helps in the synthesis of vital proteins that are used to make ligaments, skin, tendons, etc.
It also helps in tissue regeneration and absorption of iron.
Its deficiency results in a disease known as scurvy that is characterized by weakness, fatigue, capillary fragility, etc.
Vitamin C is involved in various body functions such as the synthesis of collagen, immune system, healing of the wound.
Its common sources are-
> Citrus fruits such as orange, grapefruit, and lime.
> Broccoli, Brussels sprouts, and cauliflower.
> Spinach, cabbage, and tomatoes.

Note:
Other sources of vitamin C are- strawberries, kiwi, amla, raspberries, blueberries, and cranberries. The vitamin C content of food decreases with storage and cooking because it is a water-soluble vitamin and
is destroyed by heat. But vitamin C is not found in milk. Milk is rich in thiamine.
