Vedclass · Answer

(C) The structure of $\beta-D-(-)-	ext{fructofuranose}$ is characterized by a five-membered furanose ring. In the $\beta$-anomer,the hydroxyl group $(-OH)$ at the anomeric carbon $(C-2)$ is on the same side as the $CH_2OH$ group at $C-5$. Specifically,for $D$-fructose,the $CH_2OH$ group at $C-5$ is pointing upwards. Therefore,in the $\beta$-anomer,the $-OH$ group at $C-2$ also points upwards. Comparing the given options,the structure in option $C$ correctly represents this configuration.

$\beta-D-(-)-\text{fructofuranose}$ is:
