| 2026-08-06T00:00:00+00:00 | edison_literature_identity LLM | ANNOTATED | Edison LITERATURE (PaperQA3) identity research; report at research/ingredients/Pectic_galactan_from_potato-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: **Recommended interpretation:** a **potato-derived pectic polysaccharide fraction/model substrate**, not a single defined chemical, salt, hydrate, buffer, or complete medium formulation. The best-supported structural feature is β-(1→4)-linked D-galactan. In native plant walls, such galactan generally occurs as side chains of rhamnogalacturonan I (RG-I), whose backbone alternates rhamnose and galac No ontology CURIE was proposed. 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. |
