Lipid

Vedclass · Answer

(B) The energy value of a substance is determined by the amount of energy released upon its oxidation. Lipids (fats) provide approximately $9.4 \ kcal/g$ of energy,whereas carbohydrates and proteins provide approximately $4.1 \ kcal/g$ and $4.0 \ kcal/g$ respectively. Due to the higher proportion of carbon-hydrogen bonds,lipids yield significantly more energy per gram compared to other organic macromolecules. Therefore,lipids have the highest energy value.
