JEE Main 2025 — 28 January, Evening Shift — Question 28

Match List-I with List-II

List-I (Saccharides)List_II (Glycosidic-linkages found)
(A) Sucroseα\alpha 1-4
(B) Maltose(II) α1−4\alpha 1-4 and α1−6\alpha 1-6
(C) Lactose(III) α1−β2\alpha 1-\beta 2
(D) Amylopectin(IV) β1−4\beta 1-4

Choose the correct answer from the options given below :

  1. Option A:

    (A)-(III), (B)-(I), (C)-(IV), (D)-(II)

    Correct
  2. Option B:

    (A)-(IV), (B)-(II), (C)-(I), (D)-(III)

  3. Option C:

    (A)-(II), (B)-(IV), (C)-(III), (D)-(I)

  4. Option D:

    (A)-(I), (B)-(II), (C)-(III), (D)-(IV)

Answer: A

Step-by-step solution

(A) Sucrose →α1−β2\rightarrow \alpha_{1}-\beta_{2} Glycosidic linkage

(B) Maltose →α\rightarrow \alpha 1-4 Glycosidic linkage

(C) Lactose →β\rightarrow \beta 1-4 Glycosidic linkage

(D) Amylopectin →α1−4\rightarrow \alpha 1-4 and α1−6\alpha 1-6

Glycosidic linkage A-III, B-I, C-IV, D-II
