Solution:Vitamin C is commonly referred to as ascorbic acid, while thiamine is the chemical name for Vitamin B1, citric acid is a different organic acid, and tartaric acid is another organic acid found in fruits like grapes. We have to know that the chemical formula of ascorbic acid is C6H8O6. It is also called hexuronic acid. It appears as a solid but appears yellow in impure samples. Mild acidic conditions can be obtained when it is dissolved in water and acts as mild reducing agents. We can use ascorbic acid as an additive in foods, dietary supplements. We can create volatile compounds when we mix glucose with amino acids

28. The richest source of Vitamin ‘C’ is — [Uttarakhand U.D.A./L.D.A. (Pre) 2007]

Correct Answer: (c) Orange
Solution:Indian gooseberry (amla) is the richest source of Vitamin C (Ascorbic acid). Orange, tomato, lemon, papaya, peas, etc., are also good sources of Vitamin C.

29. Which of the following vitamins is helpful for healing of a wound? [Uttarakhand P.C.S. (Pre) 2006]

Correct Answer: (c) C
Solution:Vitamin C is crucial for collagen synthesis, which is essential for wound healing. It also has antioxidant properties that help protect cells from damage and support the immune system.

While important for overall health, vitamin A's role in wound healing is not as prominent as vitamin C.

Vitamin B complex is important for various bodily functions, including energy production and nervous system health, but it is not directly involved in wound healing.

Vitamin D is essential for calcium absorption and bone health, but it does not play a significant role in wound healing.

30. Vitamin 'C' helps in absorption of which of the following elements? [U.P.U.D.A./L.D.A. (Spl) (Mains) 2010]

Correct Answer: (a) Iron
Solution:Vitamin C aids in iron absorption, while Vitamin D assists in the absorption of magnesium and calcium. Vitamin C acts as an antioxidant and can reduce ferric iron to ferrous iron, a form that is easier for the body to absorb. Vitamin C can help prevent the oxidation of ferrous iron back into ferric iron, ensuring that the absorbed iron remains available for use.

Vitamin C can form a chelate with iron, which may help to transport it across the intestinal wall and into the bloodstream. By reducing ferric iron and preventing oxidation, vitamin C significantly enhances the overall absorption of iron from food, especially non-heme iron found in plant-based sources.
