Pinitol

Pinitol is a cyclitol, a cyclic polyol. It is a known anti-diabetic agent isolated from Sutherlandia frutescens leaves.[1][2] Gall plant tannins can be differentiated by their content of pinitol.[3] It was first identified in the sugar pine (Pinus lambertiana).[4] It is also found in other plants, such as in the pods of the carob tree.[5]

Certain variants of the bacteria Pseudomonas putida have been used in organic synthesis, the first example being the oxidation of benzene, employed by Steven Ley in the synthesis of (+/-)pinitol.[6]

Glycosides

Ciceritol is a pinitol digalactoside that can be isolated from seeds of chickpea, lentil and white lupin.[7]

A cyclitol derivative can be found in the marine sponge Petrosia sp.[8]

gollark: Well, you can always read the Minoteaur source code.
gollark: I use some of this sort of tooling and you basically write stuff roughly as normal.
gollark: Nobody is going around manually editing stuff with those randomly generated names, you realize.
gollark: Blame is kind of tricky because you either end up punishing people based on random environmental details or getting stuck in unanswerable counterfactuals.
gollark: Depends how incentivized you are, probably.
