Solution


Q.

Match List I with List II                             [2025]

  List I   List II
  (Saccharides)   (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)-(II), (B)-(IV), (C)-(III), (D)-(I)  
2 (A)-(I), (B)-(II), (C)-(III), (D)-(IV)  
3 (A)-(IV), (B)-(II), (C)-(I), (D)-(III)  
4 (A)-(III), (B)-(I), (C)-(IV), (D)-(II)  

Ans.

(4)

Sucrose: Its structure consists of a glycosidic linkage between C1 of α-D-glucose and C2 of β-D-fructose.

Maltose: It is composed of two α-D-glucose units in which C1 of one glucose (I) is linked to C4 of another glucose unit (II).

Lactose: It is composed of β-D-galactose and β-D-glucose. The linkage is between C1 of galactose and C4 of glucose.

Amylopectin: It is a branched chain polymer of α-D-glucose units in which chain is formed by C1–C4 glycosidic linkage whereas branching occurs by C1–C6 glycosidic linkage.
