Concept Introduction:
Lipids are biomolecules that are involved in different biochemical reactions. They are special types of organic molecules which can only be identified 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. For example, triacylglycerol consists of three ester groups whereas Vitamin E is composed of both ether and phenolic groups. Since the size of these polar groups is negligible compared to the overall size of the organic molecule, the lipids are non-polar organic molecules which can be soluble in different organic solvents.
