The molecule is a lipid A derivative that consists of a linear tetrasaccharide phosphate comprising an N-acetyl-alpha-D-glucosamine residue,an L-glycero-alpha-D-manno-heptose residue phosphoethanolamine-substituted on O-3, another L-glycero-alpha-D-manno-heptose residue and a 3-deoxy-D-manno-oct-2-ulosonic acid (2-keto-3-deoxy-D-mannooctanoic acid, Kdo) in a (1->2), (1->3), (1->5) sequence, with the Kdo residue at the reducing end connected via an alpha(2->6) linkage to a de-O-acylated lipid A. Corresponds to the de-O-acylated lipid A conjugate of the icsB mutant of the core oligosaccharide of Neisseria meningitidis. It is a member of lipid As and a dodecanoate ester.
