JEE Main2025Jan 29, Shift 1Chemistry
Q.

Match List - I with List - II.

List - I (Carbohydrate)List - II (Linkage Source)
(A) Amylose(I) , plant
(B) Cellulose(II) , animal
(C) Glycogen(III) , , plant
(D) Amylopectin(IV) , plant

Choose the correct answer form the options given below :

  1. A

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

  2. B

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

  3. C

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

  4. D

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

Solution

Recall the structural makeup of each polysaccharide:

Amylose: linear, exclusively glycosidic bonds, plant origin (starch fraction) (IV).

Cellulose: linear, linkages, plant cell-wall component (I).

Glycogen: highly branched, along chains with branches, animal storage polysaccharide (II).

Amylopectin: branched, and linkages, plant origin (III).

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