The outer membrane contains phospholipid on its inner surface and lipopolysaccharide(LPs)on its outer surface. The space between the outer membrane and the cytoplasmic membrane is called the periplasmic space Teichoic acids do not occur in Gram-negative bacterial cell wallsThe Gram-negative cell wall is a thin layer attached to an outer membrane via lipoproteins.
