Which of the following vitamin is synthesised in the body?
Correct Answer: Vitamin-D
Description: Vitamin D is synthesized in the skin. 7-Dehydrocholesterol (an intermediate in the synthesis of cholesterol that accumulates in the skin) undergoes a nonenzymatic reaction on exposure to ultraviolet light, yielding previtamin D. This undergoes a fuher reaction over a period of hours to form cholecalciferol, which is absorbed into the bloodstream. Ref: Bender D.A. (2011). Chapter 44. Micronutrients: Vitamins & Minerals.
