3-Deoxy-D-manno-oct-2-ulosonic acid
chemical compound

3-Deoxy-d-manno-oct-2-ulosonic acid (ketodeoxyoctonic acid; KDO; IUPAC symbol Kdo) is a monosaccharide, specifically an ulosonic acid of a 2-ketooctose. In gram-negative bacteria it is a component of the core oligosaccharide portion of lipopolysaccharides, also known as endotoxin. The d-manno prefix indicates that the four chiral centers have the same configuration as d-mannose.
Begin with the source’s own compact description: “3-Deoxy-D-manno-oct-2-ulosonic acid” is chemical compound. The dossier treats that line as a proposition to test through 3-Deoxy-D-manno-oct-2-ulosonic, acid and chemical, 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.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 12, 2026. The linked authority identifier is Q1101052. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
