Chapter 19, Problem 19.81P

Interpretation Introduction

(a)

Interpretation:

An example of a monosaturated fatty acid needs to be given.

Concept introduction:

Monosaturated fatty acids are compounds with a carboxyl group, single double bond and a carbon chain of 12-20 carbons.

Interpretation Introduction

(b)

Interpretation:

An example of a wax that contains a total of 30 carbon atoms must be mentioned

Concept introduction:

Waxes are esters made up long chain alcohols and long chain carboxylic acids.

Interpretation Introduction

(c)

Interpretation:

An example of a saturated triacylglycerol needs to be given.

Concept introduction:

Triacylglycerol is also known as triglyceride. It is made up of three fatty acids forming ester bonds with one glycerol molecule.

Interpretation Introduction

(d)

Interpretation:

An example of sphingomyelin derived from ethanolamine needs to be determined.

Concept introduction:

Sphingomyelin is a sphingolipid found in animal cell membranes. They have a sphingosine backbone and phosphocholine and ceramide, or a phosphoethanolamine head group.

Ethanolamine contains a primary alcohol group and a primary amine group. Therefore, it is considered as a bifunctional organic compound.
