Question

The $\alpha$- and $\beta$- forms of glucose are

• A. isomers of D(+) glucose and L(-) glucose respectively
• B. diastereoisomers of glucose
• C. anomers of glucose
• D. isomers which differ in the configuration of C-2

Answer 1

Answer: (C)

anomers of glucose

Answer 2

The structures of $\alpha$ - and $\beta$ - forms of glucose are

Since, the two forms differ in the configuration around $C _{1}$ (anomeric carbons), these are called anomers.
