Chapter 20.10, Problem 21P

Interpretation Introduction

Interpretation:

The Haworth projection of $\alpha -\text{D}$-glucofuranose is to be drawn.

Concept Introduction:

The structural representation of sugar molecule in cyclic form is known as Haworth projection.  Sugar molecule that has six-membered-ring is known as pyranose and sugar molecule that has five-membered-ring is called furanose.  Sugar molecule in which hydroxyl groups of first and sixth carbon atom are on the same side is known as $\alpha$ sugar, otherwise $\beta$ sugar.
