A phosphate-linked oligosaccharide analogue consisting of five 3(4)-<em>O</em>-acetyl-α-<em>N</em>-acetyl-<small>D</small>-mannosaminyl residues, joined by (1→6)-phosphodiester linkages. It is a constituent 5-repeating-unit segment of <em>Neisseria meningitidis</em> serogroup A capsular polysaccharide (MenA), the structural diagram of which shows hydroxy groups partly acetylated at either positions 3 or 4, along with parts of phosphodiester linkages which are present at both the reducing and non-reducing ends of the pentasaccharide unit.
