Q. 13.32 - An Introduction to General, Organic, and Biological Chemistry

Question

What are the kind and number of atoms in the ring portion of the Haworth structure of fructose?

Step-by-Step Solution

Answer

In the cyclic shape of fructose, there are $4$ carbon atoms and an oxygen atom

Step 1: Introduction

• Typically, Haworth projections are used to demonstrate cyclic sugars. 
• It's crucial to have a smooth technique to attract sugar molecules at the same time as preserving the orientation of the $OH$ attachments as a way to discriminate among one-of-a-kind styles of sugars.

Step 2: Howarth structure of fructose

• The keto organization is positioned at $C-2$, and the carbon atoms are organized in a direct chain.
• For the $2$ anomeric sorts of $D-$ fructose, Haworth designed furanose ring systems.
• Furan is a heterocyclic ring with 5 contributors and one oxygen atom. 
• The cyclic systems of $D-$ fructose recognized as $D-$fructofuranose and $D-$ fructofuranose are primarily based totally on this.

Step 3 : Explanation

There are $4$ carbon atoms and one oxygen atom withinside the cyclic shape of fructose.
