The bacterial Gram-negative outer membrane contains:
Envelope architecture differentiates Gram staining groups morphologically and chemically. Gram-negative bacteria possess dual membrane system separated by periplasm containing thin peptidoglycan two to six nanometers and proteins, hydrolytic enzymes. Inner membrane phospholipid bilayer standard contains respiratory chain. Outer membrane asymmetric: inner leaflet phosphatidylethanolamine phosphatidylglycerol, outer leaflet predominantly lipopolysaccharides LPS molecules comprising lipid A glucosamine disaccharide with six acyl chains anchoring membrane and conferring endotoxin activity stimulat
