Complete hydrolysis of maltose yields
Correct answer: B. two glucose units
- A. glucose and fructose
- B. two glucose units
- C. glucose and galactose
- D. fructose and galactose
Explanation
Maltose is two glucose units joined by a glycosidic bond, typically produced when starch is broken down. Sucrose yields glucose plus fructose and lactose yields glucose plus galactose, so the products of hydrolysis identify the disaccharide.

About Classification of Biological Molecules
Biological molecules are classified as carbohydrates, lipids, proteins and nucleic acids, with water, minerals and vitamins also supporting cellular processes. The key distinctions involve their monomers, chemical bonds, structures and functions, including glucose and starch, fatty acids and triglycerides, amino acids and polypeptides, and nucleotides in DNA and RNA.
