A tetrasaccharide derivative composed of four arabinofuranose residues in a β(1→2), α(1→5) and α(1→5) linear sequence (with α-configuration at the reducing end), to the arabinofuranose residue at the non-reducing end is linked (3<em>P</em>→5) a 1<small>D</small>-<i>myo</i>-inositol 5-phosphate moiety.
