Although the inner leaflet of the gram-negative outer membrane is composed mainly of phospholipids, the outer leaflet of the outer membrane contains lipopolysaccharides.
Phospholipids are the most abundant component of the plasma membrane. The structure of phospholipids is composed of a backbone of glycerol containing two fatty acid chains attached to two hydroxyl groups and one phosphate group attached to the third hydroxyl group.
Lipopolysaccharides, also abbreviated as LPS, are the major component of bacterial cell wall. The role of LPS is to provide structural integrity and high permeability to the bacteria. LPS is a pyrogen and can be toxic to human body.
