In `alpha`-D-Glucose, the anomeric carbon is at:

Options

A. C-1 carbon
B. C-2 carbon
C. C-5 carbon
D. C-6 carbon

Answer

A

Explanation

D-glucose exists in two optically active forms known as `alpha`-glucose occurs such pairs differ in configuration only around `C_(1)` atom and are called anomers.

Carbon-1 in both configurations I and II is called an anomeric carbon atom.
