Lipopolysaccharide
Lipopolysaccharides (LPS), also known as lipoglycans and endotoxin, are large molecules consisting of a lipid and a polysaccharide composed of O-antigen, outer core and inner core joined by a covalent bond; they are found in the outer membrane of Gram-negative bacteria, and elicit strong immune responses in animals.The term lipooligosaccharide (""LOS"") is used to refer to a low molecular weight form of bacterial lipopolysaccharides.
