Stars
ASCII NameE. coli strain O157 LPS core oligosaccharide R3
DefinitionA branched ten-membered oligosaccharide phosphate consisting of three galactose residues, two glucose residues, one 4-phospho-D-glycero-α-D-manno-heptose residue, one L-glycero-α-D-manno-heptose residue, one 4-phospho-L-glycero-α-D-manno-heptose residue and two Kdo residues, one of which is at the reducing end. The unit constitutes one of the core oligosaccharide structures of enterobacterial lipopolysaccharide obtained from E. coli strain O157.
