lipopolysaccharides

Lipopolysaccharides (LPS) are large molecules found on the outer membrane of certain bacteria, especially Gram-negative bacteria. They consist of a lipid (fat) component connected to sugar chains. LPS play a crucial role in bacterial protection and stability. When these bacteria invade the body, the immune system recognizes LPS as a sign of infection, triggering inflammation and immune responses. Because of this, LPS can cause fever and other symptoms of illness. In medicine and research, LPS is often used to study immune reactions and inflammation, making it an important component in understanding bacterial infections and immune system behavior.
