The reason for the presence of phospholipids in cell membranes rather than triacylglycerols needs to be explained. 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 like −OH, -SH, etc. such as triacylglycerol consists of three ester groups whereas Vitamin E is composed of both ether and phenolic groups.
