Definition	A branched hexasaccharide comprising six D-arabinofuranose units, in an assembly consisting of two arabinose residues linked α(1→5) (with α-configuration at the reducing end), with α-arabinosyl-(1→2)-α-arabinosyl disaccharide units linked to the 3- and 5-positions of the residue distal from the reducing-end residue. Branched hexasaccharide from the cell wall of Mycobacterium tuberculosis.
