An organic group derived from α-<small>D</small>-Glc<em>p</em>NAc-(1→3)-[<em>P</em>-6-[CH<small><sub>2</sub></small>]<small><sub>5</sub></small>NH<small><sub>2</sub></small>]-α-<small>D</small>-Glc<em>p</em>NAc-(1→2)-<small>D</small>-GroA (CHEBI:134201) in which the 5-aminopentyl linker is replaced by a 6-(pentylamino)hexanamido one. When linked to the diphtheria toxin mutant <small><sub>197</sub></small>CRM, it shows potential as a <em>Clostridium difficile</em> vaccine candidate.
