Carbohydrates are biomolecules that also take the names of carbohydrates, carbohydrates, sugars or saccharides; although the first two names, the most common and used, are not entirely precise, since they are not strictly about hydrated carbon atoms, but attempts to replace these terms with more precise ones have not been successful. These molecules are made up of three fundamental elements: carbon, hydrogen and oxygen, the latter in a somewhat lower proportion. Its main function in the organism of living beings is to contribute to the immediate storage and obtaining of energy, especially to the brain and nervous system.
