Ontology term
CHEBI:18233 — xyloglucan
Ontology label
xyloglucan
Notes
Imported from CultureBotHT (compounds_to_cas.csv (no CAS-RN)). No CAS-RN or CHEBI mapping available; curator review needed. Reviewed on 2026-05-11 and not identity-mapped to generic xyloglucan because the source label is fraction-specific.

2026-05-11T06:02:00Z mediaingredientmech-agentic-curation LLM REVIEWED_NON_IDENTITY_PARENT UNMAPPED Left unmapped with CHEBI:18233 as a parent/narrow mapping because the source term specifies hepta, octa, and nona saccharide xyloglucan fractions rather than generic xyloglucan identity.
2026-05-11T08:14:56Z mediaingredientmech-agentic-curation LLM CLASSIFIED_FRACTION_MIXTURE UNMAPPED Classified as an undefined mixture because the source label combines hepta-, octa-, and nona-saccharide xyloglucan fractions rather than a single exact xyloglucan identity.
2026-08-06T00:00:00+00:00 edison_literature_identity LLM ANNOTATED Edison LITERATURE (PaperQA3) identity research; report at research/ingredients/Xyloglucan_heptaoctanona_saccharides-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: **Recommended interpretation:** a preparation-defined mixture/fraction of xyloglucan-derived oligosaccharides, not a single chemical and not generic polymeric xyloglucan. Complete EG-II digestion of partially purified tamarind xyloglucan yielded four principal products—XXXG, XLXG, XXLG, and XLLG—and the isolated fraction was described as containing oligosaccharides of 7–9 residues. (marry2003struc CURIEs discussed: CHEBI:18233. Recorded as provenance only — no grounding applied from this run. Edison's recommendations are deliberately conservative, and a plausible identifier promoted by a mechanism that never decided anything is what #203 and #263 exist to undo. Any CURIE above is a curator's to accept or reject.
