As with QS-21, QS-7 was shown to be a 3,28-O-bisglycoside quillaic acid, with some differences being a higher degree of glycosylation and a considerably shorter fatty acyl unit in QS-7. In the case of most saponins, one of these substituents is a sugar, so the compound is a glycoside of the base molecule. Specifically, the base or fat-soluble portion of a saponin can be a triterpene, a steroid (spirostanol or furostanol) or a steroidal alkyloid (in which nitrogen atoms replace one or more carbon atoms).
