Component
Parathyroid hormone biosynthesis
Synthesis and precursor processing of PTH, distinct from secretion of stored hormone.
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
Mg concentration did not measurably change PTH biosynthesis or proPTH-to-PTH conversion in the bovine slice experiments.
Experimental context and source evidence
- cross_nutrient
- magnesium -> PTH -> calcium
- experimental_model
- Radiolabeled leucine incorporation and precursor/hormone analysis
- limitations
- A negative result in this exposure range does not exclude synthesis defects during prolonged severe deficiency.
- nutrient_topic
- Magnesium research collection; topical membership is not evidence of a direct dietary effect. · Magnesium
- organism
- Bos taurus
- plain_language
- Mg changed release of the hormone without showing the same effect on making or processing it in this assay.
