Which pigment is fat-soluble?
Try to answer before revealing the correct option and explanation.
Correct Answer
✅ B. Chlorophyll
Explanation
Chlorophyll has long long hydrophobic phytol tail. Even though it has a polar head, the overall structure behaves largely non-polar. Therefore it dissolves better in lipids (fats and oils) than in water
Key Concept
Pigment solubility depends on molecular polarity: non-polar pigments dissolve in fats, while polar pigments dissolve in water.
