Question

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

Short answer

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

Step-by-step solution

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.

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.

Explanation

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