Interpretation: The given monosaccharide including its proper D, L designation is to be identified.
Concept introduction: Monosaccharides are the small units of simple sugars. Polysaccharides are made up of small units of monosaccharides. These small units are joined together by glycoside linkage. Carbohydrates are naturally occurring organic compounds. The monosaccharide glucose is called an Aldohexose as it contains six carbon atoms as well as an

Carbohydrates are naturally occurring organic compounds. The monosaccharide glucose is called an Aldohexose as it contains six carbon atoms as well as an aldehyde functional group and fructose is known as ketohexose as it contains six carbons with a ketone functional group.

Next, record any regiochemistry or stereochemistry considerations relevant to the reaction. You should also record any key aspects of the mechanism, such as forma- tion of an important intermediate, as a helpful reminder. You may want to keep track of all reactions that make carbon-carbon bonds, because these help you build large molecules from smaller fragments.
