Carbohydrate-lipid complex; integral substance in gram-negative cell walls. Also known as "endotoxin."
Component of the gram-negative outer membrane (OM); consists of Lipid A (the toxic portion), a core made up of a series of sugars, and the O antigen, a long carbohydrate chain; forms the outer leaflet of the gram-negative outer membrane (OM). (Lecture: The Bacterial Cell: Structure, Function, Growth, and Gene Regulation I, 1/24/02)
(LPS) A compound containing lipid bound to a polysaccharide; often a component of microbial cells walls.
A lipid attached to a polysaccharide.
a molecule containing both lipid and sugar components
a molecule made up of a lipid (a fat) with a polysaccharide (a complex sugar)
An integral part of the outer cell membrane of certain types of bacteria (so-called "gram-negative" strains).
Complex lipid structure containing unusual sugars and fatty acids found in many Gram negative bacter
Poison in bacterial outer membranes that is harmful to the body; see endotoxin
a molecule composed of fat and sugar. LPS is produced by certain bacteria and makes up part of their cell wall. When the bacteria die, the toxin is released, leading to the release of cytokines resulting in symptoms of chills, fever and possibly shock.
A compound formed by a lipid (a type of fatty substance; includes fatty acids, oils, waxes, and steroids) and a polysaccharide (a complex sugar); e.g., bacterial lipopolysaccharides.
A complex of lipid and polysaccharide (carbohydrate).
Lipopolysaccharide (LPS) is a large molecule consisting of a lipid and a polysaccharide (carbohydrate) joined by a covalent bond. LPS is a major component of the outer membrane of Gram-negative bacteria, contributing greatly to the structural integrity of the bacteria, and protecting the membrane from certain kinds of chemical attack. LPS is an endotoxin, and induces a strong response from normal animal immune systems.
