Basic StructureGonococcal lipopolysaccharide (LPS) is a complex of at least three major antigenic determinants. The ceramide part consists of the following residues : β-D-GalpNAc-(1-->3)-β-D-Galp-(1-->4)-β-D-Glcp-(1-?)-CER-(?--/Ceramide/. The core oligosaccharide part consists of the following residues : α-D-GlcpNAc-(1-->2)-L-gro [branched to β-D-Galp-(1-->4)-β-D-Glcp-(1-->4)] -α-D-manHepp-(1-->3)-L-gro-α-D-manHepp-(1-->5)-Kdo. The other part consists of the following residues : β-D-GalpNAc-(1-->3)-β-D-Galp-(1-->4)-β-D-GlcpNAc-(1-->3)-β-D-Galp-(1-->4)-β-D-Glcp-(1-->4)-L-gro [branched to α-D-GlcpNAc-(1-->2)-L-gro-α-D-manHepp-(1-->3)] -α-D-manHepp-(1-->5)-Kdo
