Chapter 13: Q. 13.68 (page 432)

What are the differences in the Haworth structures of $α$ -D-glucose and $β$ -D-glucose? (13.4)

Short Answer

Expert verified

An Anomer of a saccharide only differs in its structure at the anomeric carbon. Anomeric carbon being the functional group of the carbohydrate, which is usually the carboxyl group attached to it.

Step by step solution

Introduction

An anomer is actually anepimer (also a cyclic saccharide) that differs in configuration, particularly at the acetal or hemiacetal carbon (refer to the image below to differentiate between acetal and hemiacetal carbons).

An anomer is a kind of stereoisomer.
The anomers are saccharides or glycosides that are epimers, which are distinct from each other in the configuration at C-2.
If they are ketoses, or in the configuration of C-1, if they are aldoses.

Step 2: Differences in the Haworth structures of α-D-glucose and β-D-glucose

There are two forms of d-glucose.
These different forms, called anomers, differ only by the position of the -OH group at carbon 1.
In the a $(α)$ anomer, the $- OH$ group is drawn below the plane of the ring. In the $(β)$ anomer, the $- OH$ group is drawn above the plane of the ring.
