Which micronutrient, when deficient, can lead to scurvy due to its role as an important antioxidant?

1. Iodine

2. Vitamin D

3. Phytochemical

4. Vitamin C

The correct answer is: Vitamin C

Vitamin C is crucial for the synthesis of collagen, which is a vital protein that helps maintain the integrity of skin, cartilage, tendons, ligaments, and blood vessels. A deficiency in Vitamin C leads to a condition known as scurvy, characterized by symptoms such as fatigue, anemia, swollen gums, and bruising. This is due to the impaired collagen synthesis caused by a lack of Vitamin C. In addition to its structural role, Vitamin C also functions as an important antioxidant, helping to protect cells from damage caused by free radicals. This protective role is significant in preventing various chronic diseases and supporting the immune system. Thus, when considering the relationship between a deficiency of a specific micronutrient and the development of scurvy, it is clear that Vitamin C is the key nutrient involved. The other options relate to different aspects of nutrition and health. Iodine is primarily linked to thyroid function and prevents goiter, while Vitamin D plays a significant role in bone health. Phytochemicals are plant-derived compounds that can contribute to health in various ways but are not classified as essential vitamins or minerals.
