Three structures are given below in which two glucose units are linked. Which of these linkages between glucose units are between `C_(1)` and `C_(4)` and which linkages are between `C_(1)` and `C_(6)`?


(a)(A) is between C1 and C4, (B) and (C) are between C1 and C6
(b)(A) and (B) are between C1 and C4, (C) is between C1 and C6
(c)(A) and (C) are between C1 and C4, (B) is between C1 and C6
(d)(A) and (C) are between C1 and C6, (B) is between `C_(1)` and `C_(4)`

A

(A) is between C1 and C4, (B) and (C) are between C1 and C6

B

(A) and (B) are between C1 and C4, (C) is between C1 and C6

C

(A) and (C) are between C1 and C4, (B) is between C1 and C6

D

(A) and (C) are between C1 and C6, (B) is between `C_(1)` and `C_(4)`

Text Solution

Verified by Experts

The correct Answer is:
C
Numbering of glucose starts from adjacent carbon of O-atom to the other carbon atom ending at last `CH_(2)OH` group as shown below

In this way, numbering for the disaccharides can be done as
