Chapter 20, Problem 7RQE

Interpretation Introduction

Interpretation:

Structural formula for open-chain form for ribose, glucose, fructose, and galactose has to be drawn.

Concept Introduction:

Simplest carbohydrates are known as monosaccharides.  They contain three to six carbons generally in a chain form with a carbonyl group present in the terminal or the adjacent carbon atom from the terminal.  Monosaccharides contains only one sugar unit.

Monosaccharides can be drawn in a linear style.  Here, the hydroxyl groups are present on the each carbon atom.  Open-chain form of monosaccharide is drawn by placing the hydroxyl groups on right or left considering the chiral center.
