Chapter 16, Problem 72E

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, $\text{C}=\text{O}$ and $\text{OH}$, along its chain, and the ${\text{CH}}_2\text{OH}$ 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:
