Classify each of the following as a triglyceride, a saccharide, or an amino acid:

Chapter 16, Problem 72E, Classify each of the following as a triglyceride, a saccharide, or an amino acid: , example  1Chapter 16, Problem 72E, Classify each of the following as a triglyceride, a saccharide, or an amino acid: , example  2

Interpretation Introduction

Interpretation:

The given molecules are to be classified as triglyceride, saccharide or amino acid.

Concept Introduction:

Fats and oils are triglycerides. Triglycerides have three long hydrocarbon chains.

Carbohydrates are polyhydroxy aldehydes or ketones, or their derivatives. A carbohydrate can be identified by the presence of the functional groups, C=O and OH, along its chain, and the CH2OH group.

Carbohydrates can be classified as monosaccharides, disaccharides and polysaccharides.

The monosaccharides are composed of a single sugar unit.

The disaccharides are double-ringed structures in which two monosaccharide units are linked together.

Amino acids are the repeating structural units in a protein molecule. They contain anamino group and a carboxylic acid group, which arebonded to a central carbon atom. The structure of an amino acid is represented as follows:

Chemistry In Focus, Chapter 16, Problem 72E

Explanation of Solution

a)

The given organic molecule contains an amino group and a carboxylic acid group, which are attached to a central carbon atom. Thus, it fulfils the criterion foran amino acid.

Hence, it is an amino acid.

b)

The given molecule contains three long hydrocarbon chains in which fatty acids are bonded to the alcohol, glycerol. Thus, it fulfils the criterion for a triglyceride molecule.

Hence, it is a triglyceride...
