Carbohydrate NameLipooligosaccharide   (Drugpedia)
Carbohydrate ClassLipopolysaccharide
MicrobeMoraxella catarrhalis serotype A   (NCBI Taxonomy)   (Drugpedia)
Basic StructureLOS consists of an oligosaccharide and lipid A and is similar to the lipopolysaccharide (LPS) of gramnegative enteric pathogens, but it lacks the O-antigenic side chain of repeating units characteristic of classical LPS. The oligosaccharide part consists of the following residues : α-D-Galp-(1-->4)-β-D-Galp-(1-->4)-α-D-Glcp-(1-->2)-β-D-Glcp-(1-->6)-α-D-Glcp [branched to α-D-GlcpNAc-(1-->2)-β-D-Glcp-(1-->4)] and [branched to β-D-Glcp-(1-->3)] -(1-->5)-Kdo
