3. Proteins have a plastic or constructive function. They provide materials for cells and tissue constructions and repare and replace them. They can be “burned” to produce energy: 1 g of Proteins = 4,1 kcal Sugars or carbohydrates have an energetic function. They are main sources of energy for the body. Sugars in excess are accumulated in tissue. They can be “burned” to produce energy: 1 g of Sugars = 4,1 kcal Fats or lipids have an energetic function and contain more than double of sugars energy but their digestion is very long and complex. Fats in excess are accumulated in tissue. They can be “burned” to produce energy: 1 g of Fat = 9 kcal

4. Vitamins do a regulatory function. There are different types of vitamins and everyone does a specific function. Mineral salts have a plastic function, for tissue construction, and a regulatory function. Water is a fundamental substance for life: almost all chemical reactions are doing in water. It is present in almost all food.
