Which carbon atoms of - D glucose and - D fructose respectively forms glycosidic linkage in sucrose?
Options
- AC-1 and C-2
- BC -2 and C -1
- CC-2 and C-6
- DC-1 and C-5
Correct answer
A. C-1 and C-2
Step-by-step solution
The glycosidic linkage in sucrose forms between the anomeric carbon of α -D-glucose (C-1) and the anomeric carbon of β -D-fructose (C-2). The resulting bond is an α , β -1,2-glycosidic linkage. Carbon atoms involved are C-1 from glucose and C-2 from fructose, confirming option A.
