A low molecular mass (5 - 10Kd) pectic polysaccharide with a backbone of at least eight 1,4-linked α-<small>D</small>-Gal<em>p</em>A residues. Two structurally distinct disaccharides are attached to C-3 of the backbone and two structurally distinct oligosaccharides are attached to C-2 of the backbone. These are represented by R groups.
