Why phospholipids contain nitrogenous bases in them?

Hello Student,

Phospholipids are compound lipids and are of two types

Glycerophospholipids and sphingophospholipids

The Glycerophospholipids contain glycerol, saturated and unsaturated fatty acid, phosphoric acid and a nitrogenous base. The various glycerophospholipids are phosphatidyl choline (lecithin) Phosphatidyl serine( cephalin) Phosphatidyl ethanolamine Phosphatidyl inositol Cardiolipin and plasmalogen.

3.Sphingophospholipids contains sphingosine (instead of glycerol) fatty acid, phosphate and choline Ex: sphingomyelin CH2-O-CO-R1 CH2-O-CO-R1 CH-O-CO-R2 CH-O-CO-R2 CH2-O-phosphoric acid CH2-O-phosphoric acid-Choline phosphatidic acid Lecithin (phosphatidyl choline) phosphatidyl choline (lecithin) Contains alcohol, fatty acid, phosphoric acid and choline.
