Explanation
Glucose and fructose are monomeric saccharides, or monosaccharides. The carbon to hydrogen to oxygen (C:H:O) ratio exists in a 1:2:1 pattern indicative of a monomeric saccharide. The molecular formula of glucose and fructose is C6H12O6. Maltose is a disaccharide composed of two molecules of glucose.
