(a) Interpretation: The Fisher projection of the given monosaccharide needs to be determined and labeled as D or L sugar. Concept introduction: Fisher projection is a two dimensional representation of a three dimensional molecule. Sugar molecules can name as D or L sugars according to their most oxidized carbon at the top of the Fisher projection.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

The Fisher projection of the given monosaccharide needs to be determined and labeled as D or L sugar.

Concept introduction:

Fisher projection is a two dimensional representation of a three dimensional molecule. Sugar molecules can name as D or L sugars according to their most oxidized carbon at the top of the Fisher projection.

Interpretation Introduction

(b)

Interpretation:

The monosaccharide needs to be classified by determining the type of carbonyl group and number of carbon atoms present in it.

Concept introduction:

Monosaccharide can be characterized according to the type of carbonyl group and the number of carbon atoms in their chain. In the classification of monosaccharide based on type of carbonyl group and number of carbons present in the chain, if the monosaccharide contains an aldehyde group, the prefix aldo- is added to the name and it is called an aldose. On the other hand, if a ketone group is present, it is a ketose or the prefix keto- is added.
