Lipids contain double amount of energy as compared to the same amount of carbohydrates due to the presence of:
Correct answer: A. Higher proportion of C-H
- A. Higher proportion of C-H
- B. Higher proportion of C-O
- C. Higher proportion of Oxygen
- D. Low proportion of C-H bonds
Explanation
C-H bond is a stronger bond than the C-O bond, and since lipids contain a much higher proportion of C-H bonds than carbohydrates (because lipids contain much less oxygen per mole than carbohydrates), lipids contain double the amount of energy than carbohydrates. The remaining three options (B,C,D) are incorrect as they explain the traits of lipids in reverse.

About Lipids
Lipids include fats, oils, waxes, phospholipids and steroids, which are largely insoluble in water and soluble in organic solvents. Coverage includes glycerol and fatty acids, ester bond formation, saturated and unsaturated fats, triglyceride functions, and phospholipids in cell membranes.
