pentamannose phosphate polysaccharide
pentamannose phosphate polysaccharide
A phosphomannan in which the repeating unit consists of four α(1→3)-linked <small>D</small>-mannose residues, with the residue at the non-reducing end carrying a phosphate group at position 6, and with that at the reducing end being α(1→2)-linked to a further <small>D</small>-mannose residue; repeating units are linked from C-1 of the reducing-end mannose to an oxygen of the phosphate group at the non-reducing end.
