Both ribose and glucose are simple sugars or monosaccharides. Simple sugars are the most basic of all carbohydrates and consist of two or more hydroxyl groups and a carbonyl group attached to a five- or six-carbon ring. Sucrose is a disaccharide consisting of two monosaccharides (glucose and fructose) bonded together. Starch is a polysaccharide composed of chains of glucose molecules.
