A carbohydrate that is composed of numerous sugar molecules is called
mono) sugar (i.e. saccharide) molecule. Monosaccharide sugar molecules are also referred to as simple sugars or simple carbohydrates. Glucose, also known as blood sugar, and fructose, also known as fruit sugar, are examples of monosaccharide sugar molecules.A disaccharide is composed of two monosaccharides (i.e. two sugar molecules).Maltose, for example, is a disaccharide composed of two glucose monosaccharides, and sucrose (or table sugar) is a disaccharide composed of a glucose monosaccharide and a fructose monosaccharide.olysaccharides, also known as complex carbohydrates, are made up of many (poly means many) glucose molecules. Examples of polysaccharides include starch, glycogen, and cellulose, all of which are composed of just glucose molecules but differ in the manner in which the glucose molecules are linked together.
