Question

Identify the $\alpha- D -(-) - $ fructofuranose and $\beta-D-(-) - $ fructofuranose from the following structure.

Choose the correct option.

• A. $\alpha- D -(-)$-fructofuranose - I and II ,$\beta- D -(-)$-fructofuranose - III and IV
• B. $\alpha- D -(-)$-fructofuranose -I and III ,$\beta- D -(-)$-fructofuranose -II and IV
• C. $\alpha- D -(-)$-fructofuranose -II and III ,$\beta- D -(-)$-fructofuranose - I and IV
• D. $\alpha- D -(-)$-fructofuranose - II and IV ,$\beta- D -(-)$-fructofuranose - I and III

Answer 1

Answer: (B)

I, III $\rightarrow \alpha-D-(-)-$ fructofuranose
II, IV $\rightarrow \beta- D -(-)-$ fructofuranose
