Chapter 5, Problem 5.21P

Interpretation Introduction

Interpretation:

The stereochemical relationship between D-allose and L-glucose is to be explained.

Concept introduction:

Stereochemical relationship between molecules is categorized into enantiomers, diastereomers, constitutional isomers, same molecules, and different molecules. If two stereoisomers have inverse configuration at each corresponding chiral center, they are enantiomers of each other. If two stereoisomers have inverse configuration at some, but not all corresponding chiral centers, they are diastereomers of each other. Constitutional isomers have different connectivity of atoms.
