An additional membrane found in Gram-negative bacteria.
The outer membrane is an asymmetric lipid bilayer containing lipopolysaccharide on the external surface and proteins such as porins. It acts as a permeability barrier and contributes to antibiotic resistance and immune stimulation. Its structure is central to understanding Gram-negative bacterial physiology and pathogenicity.
