Chapter 21.1, Problem 1P

Interpretation Introduction

Interpretation:

The given monosaccharides are to be classified.

Concept Introduction:

Carbohydrates are polyhydroxy aldehyde or ketone molecules. These are also termed as biomolecules.  Carbohydrates are classified as monosaccharides, oligosaccharides and polysaccharides.

Monosaccharides are those carbohydrates, which cannot be further hydrolyzed to give simpler unit of polyhydroxy aldehyde or ketone.  Glucose, fructose, ribose, mannose and so on are the examples of monosaccharides.

The classification of monosaccharides is based on the functional group as well as number of carbon atoms present in them.  For example if ketonic group is present with three carbon atoms, then the name of the monosaccharide unit will be ketotriose.
