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
Mg depletion decreased liver crude-mitochondrial pyruvate-carboxylase activity; activity correlated positively with liver Mn concentration.
Experimental context and source evidence
- availability_state
- nutrient_deficiency Imported condition classification; unverified.
- cross_nutrient
- Mg–Mn association with PC function; no demonstration of Mn-mediated rescue.
- experimental_model
- Forty 3-week-old male Wistar rats assigned Mg-deficient or control diets for two weeks
- exposure
- Mg-deficient versus normal synthetic diet for two weeks, starting at three weeks of age.
- limitations
- Correlation does not establish direct Mn causation. No human PC metal requirement or biotin-rescue claim is inferred.
- nutrient_topic
- Manganese research collection; topical membership is not evidence of a direct dietary effect. · Manganese
- organism
- Rattus norvegicus
- plain_language
- Lower PC activity accompanied the altered manganese status during rat magnesium depletion.
