Lipids are classified into simple, complex, and derived lipids. Simple lipids include neutral fats/oils and waxes which are esters of fatty acids and various alcohols. Complex lipids contain additional components like phosphoric acid, nitrogen bases, or carbohydrates. They are further divided based on these components, such as phospholipids containing glycerol or sphingosine as the alcohol, and glycolipids containing fatty acids, sphingosine, and a carbohydrate without phosphate. Phospholipids and sphingophospholipids are subclasses of complex lipids.

Phospholipids
These are subclassified according to the type of prosthetic
group present in the lipid as follows:

12. CH3
Alcohol
Fatty acids
Phosphoric
acid
Nitrogen
base
Phospholipids

13. CH3
Phospholipids may be classified on the basis
of the type of alcohol present
Alcohol is GLYCEROL
Alcohol is SPINGOSINE
Spingomyelins
Glycerophospholipids
Spingophospholipids
