Common NameLPS (1-O-antigen)
DescriptionLipopolysaccharides (LPS), also known as lipoglycans, are large molecules consisting of a lipid and a polysaccharide joined by a covalent bond; they are found in the outer membrane of Gram-negative bacteria, act as endotoxins and elicit strong immune responses in animals. LPS consists of three parts: O antigen (or O polysaccharide), core polysaccharide and lipid A.When LPS contains a repetitive glycan polymer this is referred to as the O antigen, O polysaccharide, or O side chain of the bacteria. LPS (1-o-antigen) contains only one unit of O antigen. The O antigen is attached to the core oligosaccharide, and comprises the outermost domain of the LPS molecule. The composition of the O chain varies from strain to strain, for example there are over 160 different O antigen structures produced by different E. coli strains. The presence or absence of O chains determine whether the LPS is considered rough or smooth. Full length O-chains would render the LPS smooth while the absence or reduction of O-chains would make the LPS rough. Bacteria with rough LPS usually have more penetrable cell membranes to hydrophobic antibiotics since a rough LPS is more hydrophobic. O antigen is exposed on the very outer surface of the bacterial cell, and as a consequence, is a target for recognition by host antibodies.
