Easy MCQ +4 / -1 PYQ · JEE Mains 2025

Match List-I with List-II.

List - I (Saccharides) List - II (Glycosidic-linkages found)
(A) Sucrose (I) α 1 $-$ 4
(B) Maltose (II) α 1 $-$ 4 and α 1 $-$ 6
(C) Lactose (III) α 1 $-$ β 2
(D) Amylopectin (IV) β 1 $-$ 4

Choose the correct answer from the options given below :

  1. A <p>(A)-(III), (B)-(I), (C)-(IV), (D)-(II)</p> Correct answer
  2. B <p>(A)-(I), (B)-(II), (C)-(III), (D)-(IV)</p>
  3. C <p>(A)-(II), (B)-(IV), (C)-(III), (D)-(I)</p>
  4. D <p>(A)-(IV), (B)-(II), (C)-(I), (D)-(III)</p>

Solution

<p>(A) Sucrose $\rightarrow \alpha_1-\beta_2$ Glycosidic linkage</p> <p>(B) Maltose $\rightarrow \alpha$ 1-4 Glycosidic linkage</p> <p>(C) Lactose $\rightarrow \beta$ 1-4 Glycosidic linkage</p> <p>(D) Amylopectin $\rightarrow \alpha$ 1-4 and $\alpha$ 1-6 Glycosidic linkage</p> <p>$$\mathrm{A}-\mathrm{III}, \mathrm{~B}-\mathrm{I}, \mathrm{C}-\mathrm{IV}, \mathrm{D}-\mathrm{II}$$</p>
