Component
Bacterial reverse-mutation results for CHD-FA
Context-specific entity; species, compartment and exposure are stated on each claim.
1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What acts on it
CHD-FA did not produce a clear reproducible mutagenic response in the reported Ames tests.
Experimental context and source evidence
- evidence_access
- Primary full text
- experimental_model
- Salmonella and E. coli assays with/without S9, up to 5000 micrograms/plate.
- limitations
- The 2026 study was electronically published June 21, with a December issue date. Negative results in one assay do not erase positive or uncertain findings in another; chronic exposure remains unresolved. High-dose toxicity and a doubtful TA1537 response were reported.
