PHOSPHOLIPIDS

Most abundant lipid present in cell membrane, also called membrane lipid.
It is made up of lipid & phosphoric acid.
The basic phospholipid is phosphatidic acid.
They are respectively known as phosphatidylcholine (lecithin), phosphatidylethanolamine (cephalin), phosphatidylserine and phosphatidylinositol.
Phospholipids are amphipathic having both hydrophobic and hydrophilic ends.
Phospholipids also account for fluidity and selective permeability of membranes.
Lecithin acts as a carrier molecule, by its deficiency fatty liver disease is caused.
Cephalin present in egg yolk, nervous tissue.
Cephalin helpful in blood clotting.
Plasmogens present in brain & myelin sheath.
Sphingomyelin is a phospholipid, which do not contain glycerol.
Sphingosine is found, eg. nervous tissue.
Sphingomyelins occur in most animal membranes.
They are also present in good quantity in myelin sheath of nerve fibres.
