Lipopolysaccharide

Lipopolysaccharide (LPS) is a large molecule found on the outer membrane of certain bacteria, especially those that can cause infections. It consists of a lipid component that anchors it in the bacterial membrane and a sugar component extending outward. When these bacteria invade the body or die, LPS can be released, triggering the immune system to respond. This response can cause inflammation and fever. In research and medicine, LPS is often used to study immune reactions or to develop tests related to bacterial infections. It plays a crucial role in how the body detects and reacts to harmful bacteria.
