Chapter 16, Problem 48E

Interpretation Introduction

Interpretation:

The given R groups of fatty acids are to be classified as saturated and unsaturated, and the molecules forming solid fats are to be identified.

Concept Introduction:

Triglycerides are formed by the combination of glycerol and three fatty acids. Triglycerides have three long hydrocarbon chains.

The hydrocarbon chain contains between $7$ and $21$ carbon atoms. They are nonpolar and immiscible with water.

The fats which do not contain double bonds in their hydrocarbon chains and are solid at room temperature are known as saturated fats.

Unsaturated fats are the ones whose hydrocarbon chains contain one or more double bonds and are in the liquid state at room temperature.
