Illustrative are the conformations of the glucosides. Several other glucosides of this nature have been isolated. However, there is more benefit to this species' use of mustard oil glucosides. Of particular concern are the cyanogenic glucosides of cassava (linamarin and lotaustralin). Classification of the glucosides is a matter of some intricacy. This plant produces phytotoxic cis-cinnamoyl glucosides and cis-cinnamic acid. They are water-soluble anions and belong to the glucosides. Four diterpene glucosides have been isolated by extraction. The characteristic flavor of cabbage is caused by glucosinolates, a class of sulfur-containing glucosides. The plant also contains iridoid glucosides. The outer membrane also contains cholesterol glucosides, which are present in few other bacteria. In "Stevia rebaudiana", the biosynthesis of the glucosides occurs only in green tissues. Iridoid glucosides have been isolated from "T. laurifolia". These include monoterpenoid glucosides, flavonoids, tannins, stilbenoids, triterpenoids, steroids, paeonols, and phenols. The glucosides are transported through the cell membrane to the apoplast.
