Chapter 16.2, Problem 2P

Interpretation Introduction

Interpretation:

The Fischer projections of $L-glu\cos e$ and $L-fructose$ structures have to be drawn.

Concept Introduction:

Fischer projection of a molecule is a type of two-dimensional representation of organic molecules.  It was proposed by Hermann Emil Fischer in $1891$.  It was specially proposed for the identification of carbohydrates and used by chemists particularly in organic chemistry and biochemistry.

In Fischer projection carbon chain is depicted vertically.  All the carbon atoms of the chain are represented by the center of the crossing line.  The functional group like ketone group has the lowest possible priority two and the aldehydic group has the lowest priority one.
