Answer and Explanation:
Carbohydrates are a type of biomolecule that the body uses primarily for energy and/or structure. They usually consist of the elements carbon (C), hydrogen (H), and oxygen (O) in a 1 : 2 : 1 ratio. For example, glucose, a carbohydrate, is .
Monomers of carbohydrates are called monosaccharides, and polymers are called disaccharides if two monosaccharides are combined and polysaccharides if more than two monosaccharides are put together.
Examples of carbohydrates are sugars, starches, cellulose, lactose, sucrose, etc.
