Question

Give one example each of a fat-soluble vitamin and a water-soluble vitamin.

Hint:

Vitamins A, D, E and K are fat-soluble, whereas Vitamin B-complex and Vitamin C are water-soluble vitamins.

Answer 1

Step 1: Basis of classification.
Vitamins are classified by solubility: fat-soluble types (A, D, E, K) dissolve in fats and oils and are stored in body tissues, while water-soluble types (B-complex, C) dissolve in water and are not stored significantly.
Step 2: Example of a fat-soluble vitamin.
Vitamin A (retinol) is a fat-soluble vitamin essential for vision, growth, and maintaining healthy epithelial tissue.
Step 3: Example of a water-soluble vitamin.
Vitamin C (ascorbic acid) is a water-soluble vitamin essential for collagen synthesis, wound healing, and immune function.
