2026-05-11T07:56:05Z mediaingredientmech-agentic-curation LLM REVIEWED_METAL_NTA_COMPLEX UNMAPPED Classified as a single metal-NTA complex and left unmapped because no exact local ontology term for zinc-NTA was verified; generic NTA or zinc mappings would not preserve complex identity.
2026-08-06T00:00:00+00:00 edison_literature_identity LLM ANNOTATED Edison LITERATURE (PaperQA3) identity research; report at research/ingredients/Zinc-NTA-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: **Recommended interpretation:** “Zinc-NTA” is best treated as an under-specified label for a **zinc(II)–nitrilotriacetate coordination complex**, rather than as free zinc, free nitrilotriacetic acid/NTA, a buffer, or a commercial mixture. A biological study explicitly describes Zn²⁺–NTA as an anionic complex and reports strong zinc binding, with a stated zinc dissociation constant of 17 nM. This s 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.
