Which nutrient provides energy and is formed from glycerol, delivering about 9 calories per gram?

Explanation:
Fats (lipids) store the most energy per gram among the macronutrients. They are mainly triglycerides, formed from a glycerol backbone attached to three fatty acids. When metabolized, fats yield about 9 calories per gram, which is more energy-packed than carbohydrates or proteins (about 4 kcal/g each). Vitamins don’t provide energy. So the nutrient described is fats.
