Chapter 24, Problem 55PP

(a)

Interpretation Introduction

Interpretation:

Name for given compounds should be identified.

Concept introduction:

The Haworth projection: A Haworth projection is a three-dimensional representation of monosaccharides and the structural formula is inscription as a cyclic structures.

In Haworth projection, oxygen atom is placed in back right corner, ${\text{CH}}_{\text{2}}\text{OH}$ is arranged up at the C5 carbon atom because it is D form. Anomeric hydroxyl group is placed down if it is α-anomer which is trans to the ${\text{CH}}_{\text{2}}\text{OH}$ of C5 carbon. The remaining hydroxyl group is placed up if the hydroxyl group left side in Fischer projection. Hydroxyl group is placed down if the hydroxyl group right side in Fischer projection.

Furanose: A five-member closed chain form of a monosaccharide.

Pyranose: A six-member cyclic form of a monosaccharide.

To find: Name of given molecule.
