• N. meningitidis serogroup A (MenA) DP3

Definition

A phosphate-linked oligosaccharide analogue consisting of three 3(4)-O-acetyl-alpha-N-acetyl-D-mannosaminyl residues, joined by a (1->6)-phosphodiester linkages. It is a constituent 3-repeating-unit segment of Neisseria meningitidis 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 trisaccharide unit.
