Common NameRa-LPS
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. There are 2 forms of LPS: smooth-form and rough-form. The smooth-form (S-form) LPS consists of three parts: O antigen (or O polysaccharide), core region and lipid A. The rough-form (R-form) LPS only consists of core region and lipid A. The Core domain always contains an oligosaccharide component which attaches directly to lipid A and commonly contains sugars such as heptose and 3-deoxy-D-mannooctulosonic acid (also known as KDO, keto-deoxyoctulosonate). Depending on the quantity and composition of the sugars in the core region, E. coli K-12 R-form LPS can be classified as Ra, Rb1, Rb2, Rc, Rd1, Rd2, and Re-LPS. LPS is first synthesized as KDO-lipid A or Re-LPS. Adding more sugars to the core region gives rise to Rd, Rc, Rb and Ra-LPS. (Wikipedia; PMID: 17403049 ; PMID: 17364071 ; PMDI: 20203010)
