Chapter 19, Problem 19.54P

Interpretation Introduction

(a)

Interpretation:

The fatty acids that are used to form the given triacylglycerol should be determined.

Concept Introduction:

Triacylglycerols are esters that are formed by reacting three molecules of fatty acids with one molecule of glycerol. If all the three fatty acids are identical it is called a simple triacylglycerol and if there are two or more different fatty acids, it is called a mixed triacylglycerol. Depending on whether the fatty acids involved are saturated or unsaturated, there are two types of triacylglycerols.

Interpretation Introduction

(b)

Interpretation:

Whether the triacylglycerol is expected to be a solid or a liquid at room temperature should be determined.

Interpretation Introduction

(c)

Interpretation:

Hydrophobic regions in the triacylglycerol should be labeled.

Interpretation Introduction

(e)

Interpretation:

Hydrolysis products that are formed when the triacylglycerol is treated with aqueous sulfuric acid should be determined.
