Lipopolysaccharides

Medical Definition: Lipid-containing polysaccharides which are endotoxins and important group-specific antigens. They are often derived from the cell wall of gram-negative bacteria and induce immunoglobulin secretion. The lipopolysaccharide molecule consists of three parts: LIPID A, core polysaccharide, and O-specific chains (O ANTIGENS). When derived from Escherichia coli, lipopolysaccharides serve as polyclonal B-cell mitogens commonly used in laboratory immunology. (From Dorland, 28th ed)
Guide Notes: largely bacterial so do not coord with POLYSACCHARIDES, BACTERIAL for bacterial lipopolysaccharides; coord IM with specific bacterium (IM); DF: LPS
