5-Deoxyinositol
chemical compound
5-Deoxyinositol (quercitol) is a cyclitol. It can be found in wines aged in oak wood barrels. It can also be found in Quercus sp. (oaks) and in Gymnema sylvestre. It is different from quercetol, a synonym of quercetin.
Biosynthesis
The proposed biosynthesis of 5-deoxyinositol begins with the conversion of D-glucose to myo-inositol. In this pathway, D-glucose is phosphorylated to form D-glucose-6-phosphate. The NAD+ dependent enzyme inositol 1-phosphate synthase (I1PS) then catalyzes the subsequent oxidation, enolization, aldol cyclization, and reduction of D-glucose 6-phosphate to form myo-inositol 1-phosphate. Hydrolysis of the phosphate group on this molecule gives myo-inositol. Myo-inositol can then be converted into 5-deoxyinositol in three steps, beginning with the oxidation of myo-inositol by inositol dehydrogenase (ID) to form scyllo-inosose.
Begin with the source’s own compact description: “5-Deoxyinositol” is chemical compound. The dossier treats that line as a proposition to test through 5-Deoxyinositol, chemical and compound, not as a finished interpretation.
Why this record matters
The phrase “chemical compound” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Dec 3, 2025. The linked authority identifier is Q4639585. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
