Chapter 21.10, Problem 20P

a)

Interpretation Introduction

Interpretation:

The structure of the given sugar $\beta$-D-galactopyranose is to be drawn by using Haworth projections.

Concept Introduction:

Haworth projections are used to represent the cyclic structures of the monosaccharides. In other words,

“A common way of writing a structural formula to represent the cyclic structure of monosaccharide with a simple three-dimensional perspective is called Haworth projection”.

b)

Interpretation Introduction

Interpretation:

The structure of the given sugar $\alpha$-D-tagatopyranose is to be drawn by using Haworth projections.

Concept Introduction:

Haworth projections are used to represent the cyclic structures of the monosaccharides. In other words,

“A common way of writing a structural formula to represent the cyclic structure of monosaccharide with a simple three-dimensional perspective is called Haworth projection”.
