MeSH Heading: Lipopolysaccharides
Tree Number(s): D09.400.500; D09.698.718.450; D10.494; D23.050.161.616.525; D23.946.123.329.500
Unique ID: D008070
RDF Unique Identifier: https://id.nlm.nih.gov/mesh/D008070
Annotation: oordinate with specific bacterium if pertinent
Scope Note: 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)
