Fischer projection formula of D - $(-)$ - fructose is
Fischer projection formula of D - $(-)$ - fructose is
Solution
The Fischer projection of D-(-)-fructose is determined by the configuration of its chiral centers, specifically the lowest chiral carbon (C5).
Key Features of D-(-)-Fructose:
- D-Configuration: The \(-O H\) group on the lowest chiral carbon (C5) must be on the right side.
- Structure at C3: In fructose, the \(-O H\) group at the C3 position is on the left side.
- Functional Group: It is a ketohexose, with the ketone group (\(C=O\)) at the \(\mathrm{C 2}\) position.
