What is the precursor to Vitamin A found in plants?

• A. Retinol
• B. Beta carotene
• C. Cholecalciferol
• D. Ascorbic acid

Answer: (B)

Beta carotene is the correct answer because it is a plant-derived pigment that serves as a precursor to vitamin A. In the body, beta carotene is converted into retinol, the active form of vitamin A, which is essential for various bodily functions including vision, immune function, and skin health.

Retinol itself is an animal-derived form of vitamin A and not found in plants. Cholecalciferol is a form of vitamin D3 and is not related to vitamin A. Ascorbic acid, known as vitamin C, plays a different role entirely in the body, focusing primarily on antioxidant properties and collagen synthesis rather than serving as a precursor to vitamin A. Thus, beta carotene from plant sources is crucial for those looking to increase their vitamin A levels through vegetarian or vegan dietary choices.
