Carbohydrates are organic compounds made primarily of three elements: carbon (C), hydrogen (H), and oxygen (O). The general formula for carbohydrates can be represented as Cn(H2O)n, where ‘n’ represents the number of carbon atoms in the molecule.
These elements combine in specific ratios to create various types of carbohydrates, including simple sugars (like glucose and fructose) and complex carbohydrates (such as starch and cellulose). The carbon atoms form the backbone of the molecule, while hydrogen and oxygen help to complete the structure, contributing to the functional properties of carbohydrates.
In essence, the presence of these three elements is crucial for the formation of carbohydrates, which serve as essential biomolecules for energy storage and supply in living organisms.
