Lipids are classified as simple, compound and derived based on their constituents.
Simple lipids are esters of fatty acids with alcohol e.g., oil, wax, and fats.
Compound lipids are esters of fatty acids with alcohol and with an additional group. Phospholipids which are simple lipids with a phosphate group are examples of compound lipids.
Derived lipids are substances derived from simple or compound lipids by hydrolysis. Examples are steroid, carotenoid and cholesterol.
Arachidonic acid is a fatty acid with 20 carbon atoms. It is not a derived lipid.
