Chapter 24.5, Problem 19CC
(a)
Interpretation Introduction
Interpretation:
Furanose forms of D-Erythrose and D-Threose are needed to be drawn.
Concept introduction:
- Furanose is used to represent sugars in their cyclic forms. In which five-membered ring consisting of four carbon atoms and one oxygen atom.
- The –OH group of C4 carbon attacks the carbonyl group of the D-aldotetroses, thereby a Furanose ring is formed by the four carbon atoms and oxygen atom of –OH group in the C4 carbon with incorporating into the ring.
- α-indicates the –OH group of anomeric carbon C1 is directed to down side.
- β-indicates the –OH group of anomeric carbon C1 is directed to upward side.
- The right side and left side –OH groups of chiral carbons in fisher projection are drawn as down side and upward side respectively.
To draw: the Furanose form of α-D-Erythrofuranose.
