Lipopolysaccharides (LPS) are large molecules consisting of a lipid and a polysaccharide that are bacterial toxins. They are composed of an O-antigen, an outer core, and an inner core all joined by a covalent bond, and are found in the outer membrane of Gram-negative bacteria. Today, the term … Prikaži več The toxic activity of LPS was first discovered and termed endotoxin by Richard Friedrich Johannes Pfeiffer.
