Lipopolysaccharide (LPS), now more commonly known as endotoxin, is a collective term for components of the outermost membrane of the cell envelope of Gram-negative bacteria, such as E. coli and Salmonella with a common structural architecture. Lipopolysaccharides are large molecules consisting of three parts: an outer core polysaccharide termed the O-antigen, an inner core oligosaccharide and lipid A (from which toxicity is largely derived), all covalently linked.
