Which vitamin is also known as L-ascorbic acid and found in citrus fruits?

The correct answer is Vitamin C, which is indeed known as L-ascorbic acid. This vitamin is vital for numerous bodily functions, including the formation of collagen, absorption of iron, and maintenance of the immune system. Citrus fruits like oranges, lemons, and grapefruits are particularly rich in Vitamin C, which makes them excellent dietary sources.

In addition to its role in collagen synthesis, Vitamin C acts as a potent antioxidant, helping to protect cells from damage caused by free radicals. This is why many people consider citrus fruits to be health-promoting, especially in preventing scurvy, a disease that arises from Vitamin C deficiency.

The other vitamins listed—A, E, and D—have distinct roles and functions within the body, such as vision and skin health for Vitamin A, antioxidative properties for Vitamin E, and regulation of calcium and phosphate for Vitamin D. However, they do not pertain to the acid form commonly referred to as L-ascorbic acid or share the same dietary sources associated with citrus fruits.
