Fats are composed of the same three elements as carbohydrates—carbon, oxygen and hydrogen. However, they are much poorer in oxygen and richer in carbon and hydrogen than are carbohydrates. Because of this higher carbon and hydrogen content, fats have a greater heat or energy equivalent than carbohydrates. | Fats are composed of the same three elements as carbohydrates—carbon, oxygen and hydrogen.
