1 Lipids: Fats & Steroids Lipids are natural plant & animal products more soluble in non-polar solvents like gasoline than in water. Combustion of one gram: of carbohydrate produces 4 to 5 Calories, protein produces 4 to 5 Calories, fat produces 9 to 10 Calories — more than twice that of either sugars or proteins.
