Chapter 8, Problem 5E

Summary Introduction

To draw: The structure furanose and pyranose forms of D-ribose.

Concept introduction:

The biomolecules that are composed of carbon, hydrogen, and oxygen is collectively called as carbohydrates. They are also known as sugars or saccharides. They act as a major source of food and play an important role to supply energy to the organisms. D-ribose contains five-carbon sugars and is one of the important components of ribonucleotide RNA residues. The furanose and pyranose are the cyclic sugars. The furanose has a five membered ring and pyranose has a six membered ring.
