Chapter 25, Problem 25.9P
Interpretation Introduction

Interpretation:

In aldopentose, the carbon which determines the D and L configurations has to be determined.

Concept Introduction:

The D and L configurations can be defined by the –OH group present on the penultimate carbon.  If the –OH group is present on the right side of the carbon atom, it is said to be D-form (dextrorotatory form).  If the –OH group is present on the left side of the carbon atom, it is said to be L-form (levorotatory form).
