Carbohydrate ClassLipopolysaccharide
MicrobePseudomonas aeruginosa   (NCBI Taxonomy)   (Drugpedia)
Basic StructureThe LPS consists of three regions, namely O-polysaccharide, core oligosaccharide and lipid A. The core region of LPS is divided into the outer core and inner core. The inner core region consists of 2-keto-3-deoxyoctonic acid (KDO), heptose, phosphate, and probably ethanolamine. The outer core region commonly contains D-glucose, L-rhamnose, D-galactosamine, and L-alanine. The O-antigens consist of a trisaccharide repeating unit which consists of two uronic acid derivatives and one N-acetyl fucosamine residue
