apiogalacteronin
A pectic compound characterized by a backbone of α-(1→4)-linked <small>D</small>-galacturonic acid residues substituted with apiose and apiobiose (<small>D</small>-apiofuranosyl-β-(1→3)-<small>D</small>-apiose) side chains via O-2 or O-3 links. These are represented by R groups in the structure.
