2026-05-11T08:14:56Z mediaingredientmech-agentic-curation LLM REVIEWED_POLYMER UNMAPPED Classified as a single polymer ingredient and left unmapped because the R-specific surface form lacks CAS/stereochemistry support for safe merge to the existing poly(3-hydroxybutyric acid) mapped record.
2026-08-06T00:00:00+00:00 edison_literature_identity LLM ANNOTATED Edison LITERATURE (PaperQA3) identity research; report at research/ingredients/PolyR-3-hydroxybutyric_acid-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: **Recommended interpretation:** a **single stereospecific polymer ingredient**, namely the homopolyester **poly[(R)-3-hydroxybutyrate]**, commonly abbreviated **PHB**, **P3HB**, or **P(3HB)**. The source label uses “hydroxybutyric acid,” but polymer nomenclature in the literature more commonly uses “hydroxybutyrate.” PHB is an intracellular bacterial carbon- and energy-storage polyester and a shor 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.
