Chapter 19, Problem 54P

Interpretation Introduction

Interpretation:

The correct example of phospholipid needs to be determined.

Concept Introduction:

Lipids are biomolecules that are involved in different biochemical reactions. In general, lipids contain a large number of C-C and C-H bonds with few polar functional groups such as −OH, -SH, etc. For example, triacylglycerol consists of three ester groups whereas Vitamin E is composed of both ether and phenolic groups.

Phospholipid is type of lipid that contains a phosphorus atom. They are mainly found in cell membrane of plants and animals. They are also called as phosphoacylglycerol as two fatty acids with phosphate group and alcoholic group are bonded to the glycerol molecule through ester linkage. Because of the presence of ester linkage between glycerol and fatty acids, phospholipids are hydrolyzable lipids.
