Question

Write two sources of vitamin C.

Answer 1

Hint: Vitamin C is a water-soluble vitamin that is commonly found in varying quantities in fruits and vegetables and performs various functions in the body. It is not synthesized endogenously in the body.

Complete answer: 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.

Its common sources are-
1. Citrus fruits such as orange, grapefruit, and lime.
2. Broccoli, Brussels sprouts, and cauliflower.
3. Spinach, cabbage, and tomatoes.

Additional information: Vitamin C is involved in various body functions such as the synthesis of collagen, immune system, healing of the wound, and maintenance of cartilage, bones, and teeth. It also acts as an important physiological antioxidant.

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.
