Chapter 19.7, Problem 19.18P

Interpretation Introduction

Interpretation:

The reason for the phospholipids rather than triacylglycerols present in cell membranes should be explained.

Concept Introduction:

Triacylglycerols are also known as triglycerides. They are formed by the combination of glycerol and three molecules of fatty acids. The final triglyceride structure contains three ester parts in it. Triacylglycerols hydrolyze in water in the presence of acidic or basic medium. Hydrolysis of Triacylglycerols produces three molecules of fatty acids and glycerol. All three side chains present there is non-polar in nature.

Phospholipids consist of a hydrophilic polar head and two nonpolar tails composed of C-Cand C- H bonds.
