    Triacylglycerols Are Highly Concentrated Energy Stores ...

    Triacylglycerols are highly concentrated stores of metabolic energy because they are reduced and anhydrous. The yield from the complete oxidation of fatty acids is about 9 kcal g1 (38 kJ g1), in contrast with about 4 kcal g1 (17 kJ g1) for carbohydrates and proteins. The basis of this large difference in caloric yield is that fatty acids are much more reduced.
