Concept Introduction:

Lipids are biomolecules which are involved in different biochemical reactions.They are special types of organic molecules which can only identify with the help of their physical properties, not by the presence of any certain functional group. In general, lipids contain a large number of C-C and C-H bonds with few polar functional groups such as −OH, -SH, etc.like 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.
