What is the correct explanation of the non-reducing property of sucrose?

Options

  1. Aα -D-glucopyranose and β -D-fructofuranose are linked via C 2 and C 1 centres respectively
  2. Bα -D-glucopyranose and β -D-fructofuranose are linked via C 1 and C 2 centres respectively
  3. Cα -D-glucopyranose and β -D-fructofuranose are linked via C 2 and C 2 centres respectively
  4. Dα -D-glucopyranose and β -D-fructofuranose are linked via C 3 and C 4 centres respectively

Correct answer

B. α -D-glucopyranose and β -D-fructofuranose are linked via C 1 and C 2 centres respectively

Step-by-step solution

Sucrose is a non-reducing sugar since, both glucose ( C 1 - α ) and fructose ( C 1 - β ) are connected to each other through their reducing centers.
