Question

The viatmin which is hydrophobic in nature

• A. Vitamin C
• B. Vitamin E
• C. Vitamin B2
• D. Vitamin B6

Hint:

Mnemonic to remember fat-soluble (hydrophobic) vitamins: KADE (Vitamins K, A, D, E).
These vitamins require dietary lipids for optimal absorption in the gut and can be stored in the liver and adipose tissue.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Vitamins are essential organic micronutrients classified into two major categories based on their chemical solubility:
1. Water-soluble (hydrophilic) vitamins: Vitamin C and the Vitamin B-complex series.
2. Fat-soluble (hydrophobic) vitamins: Vitamins A, D, E, and K.
Detailed Explanation:
Let us analyze the chemical nature of the given vitamins:
- Vitamin C (Ascorbic acid): A highly polar, water-soluble molecule that acts as a reducing agent and antioxidant in aqueous compartments. It is hydrophilic.
- Vitamin E (Tocopherols and Tocotrienols): This vitamin family contains long isoprenoid hydrophobic hydrocarbon tails attached to a chromanol ring.
Its hydrophobic nature causes it to partition into lipid bilayers and adipose tissues, where it acts as a primary antioxidant protecting cell membranes from lipid peroxidation.
- Vitamin B2 (Riboflavin): A water-soluble vitamin that serves as the precursor for coenzymes FMN and FAD. It is hydrophilic.
- Vitamin B6 (Pyridoxine): A water-soluble vitamin that serves as the precursor for pyridoxal phosphate (PLP). It is hydrophilic.

Step 2: Final Answer:
Vitamin E is the fat-soluble, hydrophobic vitamin among the options.
