Component
2S,6S-/2S,6R-6-(2-Oxopropyl)piperidine-2-carboxylate
Independent small molecule record; interpretation is limited by each linked claim and its study context.
2 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 it acts on
Exposure to 10 mM 2-OPP increased zebrafish larval hyperactivity.
Experimental context and source evidence
- experimental_model
- Wild-type Tüpfel long fin zebrafish F4 larvae exposed to 10 mM 2-OPP.
- limitations
- Classic convulsions were absent; this does not prove human seizure causation. This exposure arm did not have ALDH7A1 impairment; it is not a genetic-deficiency experiment.
- organism
- Danio rerio
- plain_language
- A disease-associated metabolite affected an animal behavior assay.
