1. Simple lipids: - Simple lipids are the esters of fatty acids and can be further divided into: -
Waxes: - Esters of high fatty acids with alcohol.
Fats: - Eaters of higher fatty acids with glycerol.
For example Triglycerol etc.
2. Compound lipids: - Compound lipids are those lipids that contain other groups as well in addition to alcohol and glycerol. They can be further categorised into:
For example: Cephalin, Gangliosides etc.
3. Derivatives lipids: - When lipids consist of a hydrocarbon ring and a long chain of hydrocarbons they are called derivatives
For Example: Steroids, Cholesterol etc.
