Quick Answer. Carbohydrate monomers are called monosaccharides, which are also known as simple sugars. They are composed of either five or six carbons that have a ring-like structure and form a single sugar. Examples of monomers are glucose, fructose and galactose, which are all simple sugars.
Monosaccharides are the simplest carbohydrates in that they cannot be hydrolyzed to smaller carbohydrates. They are aldehydes or ketones with two or more hydroxyl groups. The general chemical formula of an unmodified monosaccharide is (Câ¢H 2 O) n, literally a carbon hydrate..ollowing this definition, some chemists considered formaldehyde (CH 2 O) to be the simplest carbohydrate, while others claimed that title for glycolaldehyde. Today the term is generally understood in the biochemistry sense, which excludes compounds with only one or two carbons.
