For each of the monosaccharides shown in Table 21-8 the sugars as aldohexoses, aldopentoses, ketohexoses or ketopentoses are to be classified. Concept introduction: Carbohydrates are naturally occurring organic compounds. As the name implies carbohydrates are hydrates of carbon and have general formula of C X ( H 2 O ) Y . Basically, carbohydrates are polyhydroxy aldehyde and ketones , for examples, glucose and fructose. Sugars are classified by the number of carbon atoms and functional group they contains. 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. To determine: The classification of sugars as aldohexoses, aldopentoses, ketohexoses or ketopentoses.

Solution Summary: The author explains the classification of the monosaccharides in Table 21-8.
Definition Definition Group of atoms that shape the chemical characteristics of a molecule. The behavior of a functional group is uniform in undergoing comparable chemical reactions, regardless of the other constituents of the molecule. Functional groups aid in the classification and anticipation of reactivity of organic molecules.

Interpretation Introduction
Interpretation: For each of the monosaccharides shown in Table
21-8 the sugars as aldohexoses, aldopentoses, ketohexoses or ketopentoses are to be classified.
Concept introduction: Carbohydrates are naturally occurring organic compounds. As the name implies carbohydrates are hydrates of carbon and have general formula of
CX(H2O)Y. Basically, carbohydrates are
polyhydroxyaldehyde and ketones, for examples, glucose and fructose. Sugars are classified by the number of carbon atoms and functional group they contains. 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.
To determine: The classification of sugars as aldohexoses, aldopentoses, ketohexoses or ketopentoses.
