What does hydrolysis of sucrose yield?

What does hydrolysis of sucrose yield?

• A. Glucose only
• B. Galactose and glucose
• C. Maltose and glucose
• D. Fructose and glucose

Answer: (D)

Hydrolysis of a disaccharide breaks the bond between the two monosaccharide units, adding a molecule of water to yield the individual sugars. Sucrose is made of glucose linked to fructose, so when it is hydrolyzed it yields glucose and fructose. Enzymes like sucrase (invertase) in the intestine perform this reaction, producing an equimolar mix of glucose and fructose (invert sugar). The other options reflect hydrolysis products of different disaccharides: lactose gives glucose and galactose, and maltose gives two glucose units.
