The first 2 is fat. Carbohydrates than fats, are more "enrichment" of the food and energy, but it is only used as a storage and the energy is not immediately available. The first 3 is a protein. Protein is determined by the carbon, hydrogen, oxygen and ammonia elements of large molecules made up of.
