Question

Which carbon is anomeric carbon in $\alpha -\text{Fructose}$?

• A. $C_1$
• B. $C_2$
• C. $C_3$
• D. $C_6$

Answer 1

The correct option is B $C_2$

In carbohydrate chemistry, diastereomers differing only at the hemiacetal or acetal carbon are called anomers, and the hemiacetal or acetal carbon atom is ​called the anomeric carbon atom. ​𝛼-form & 𝛽-form, are ​called anomers.​The correct structure of $\alpha -\text{Fructose}$ is
Hence $C_2$ carbon is anomeric carbon.
