NCIT:C944— Vitamin - Ontology label
- Vitamin
- Notes
- CultureMech placeholder_id: 8; reviewed on 2026-05-11 and left unmapped because "Vitamin B" is ambiguous and the raw Vitamin B12 surface form should not force identity mapping to either B vitamin or cobalamin; classified as an undefined mixture/category term rather than a specific ingredient.

| 2026-05-11T05:44:00Z | mediaingredientmech-agentic-curation LLM | REVIEWED_AMBIGUOUS_VITAMIN_TERM | UNMAPPED | Left unmapped because the record combines a broad "Vitamin B" label with a Vitamin B12 raw source synonym. Removed CAS-RN 98-92-0 from the ambiguous record because that CAS is locally represented by mapped nicotinamide, not by the whole B-vitamin group. |
| 2026-05-11T10:05:00Z | mediaingredientmech-agentic-curation LLM | CLASSIFIED_AMBIGUOUS_VITAMIN_TERM | UNMAPPED | Set ingredient_type=UNDEFINED_MIXTURE because the label is a broad B-vitamin category and the raw source synonym conflicts with a specific Vitamin B12 identity. |
| 2026-08-06T00:00:00+00:00 | edison_literature_identity LLM | ANNOTATED | Edison LITERATURE (PaperQA3) identity research; report at research/ingredients/Vitamin_B-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: **Recommendation: retain `UNMAPPED` and `UNDEFINED_MIXTURE`.** The bare label **“Vitamin B” is not a single chemical identity**. In modern nomenclature, the B complex comprises eight distinct vitamins: B1/thiamine, B2/riboflavin, B3/niacin, B5/pantothenic acid, B6/pyridoxine-family vitamers, B7/biotin, B9/folate, and B12/cobalamins. These compounds do not share one molecular formula, salt state, c CURIEs discussed: NCIT:C944. 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. | |

(Cyanocobalamin)' (x1 CultureMech mentions). Source: culturemech:output/ingredient_occurrences.tsv. |
