Three structures are given below in which two glucose units are linked. Which of these linkages between glucose units are between C1 and C4 and which linkages are between C1 and C6?



The linkages between C1 and C4 of glucose are represented in the picture as ‘A’ and ‘C’ and ‘B’ is the linkage between C1 and C6 of the glucose units. Also, upon looking at the structures it is clear that option (iii) is correct.


Option (ii) is incorrect because ‘B’ is the linkage between C1 and C6 of the glucose units.


Option (i) is incorrect because ‘C’ is the linkage between C1 and C4 of the glucose units.


Option (iv) is incorrect because ‘A’ is the linkage between C1 and C4 of the glucose units.
