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
The potassium-induced increment in glucose-derived carbon-14 acetylcholine was 75% lower in deficient rat brain slices.

- cross_nutrient
- Links thiamine-dependent carbon metabolism with synthesis of a choline-containing transmitter; no choline repletion outcome was tested.

- declined by 50 and 75%, respectively
- experimental_model
- Symptomatic pyrithiamine-induced thiamine-deficient rats; brain slices assayed with uniformly carbon-14-labeled glucose at rest and during potassium stimulation; seven-day thiamine reversal arm.
- exposure
- Pyrithiamine-induced deficiency followed by potassium stimulation of rat brain slices
- limitations
- This tracer experiment did not test choline deficiency or choline supplementation; synthesis labeling is not transmitter release.
