Hydrolysis of sucrose gives:
  1. (A)α - D - (+) - Glucose and α - D - (-) - Fructose
  2. (B)α - D - (-) - Glucose and α - D - (+) - Fructose
  3. (C)α - D - (+) - Glucose and β - D - (-) - Fructose✓ Correct
  4. (D)α - D - (-) - Glucose and β - D - (-) - Fructose

Answer: (C)

Solution

Sucrose is a non-reducing disaccharide in which the glycosidic linkage joins the form of glucose to the form of fructose. Acidic or enzymatic hydrolysis cleaves this linkage and releases both units in those configurations. Hydrolysis of sucrose gives -D--glucose and -D--fructose.
