Description: The molecule is an oligosaccharide derivative that is a undecasaccharide derivative, the oligosaccharide portion of the Proteus penneri strain 13 lipopolysaccharide (LPS) core region. Structural variations can occur: the alpha-LD-Hep substituent linked (1->7) to alpha-LD-Hep6PEtn may be further substituted (1->7) by a beta-D-GalAN residue; if so, then the [alpha-LD-Hep-(1->2)-alpha-DD-Hep branch linked (1->2) to alpha-D-GalA may be absent.
