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.

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 acts on

  1. Other tested metals competed for zinc binding to purified FTS; this is not a demonstrated dietary-metal antagonism in vivo.

    A separate binding study reported an apparent zinc dissociation constant of **(5 ± 2) × 10⁻⁷ M at pH 7.5** and no detectable binding below pH 6 under its assay conditions. Other tested metals competed for binding. These are purified-system measurements, not a threshold for dietary intake, plasma zinc or thymulin failure inside a patient. They make pH and competing ligands relevant experimental variables. [Zinc-binding study, 1984](https://pubmed.ncbi.nlm.nih.gov/6538097/)

What acts on it

  1. Purified FTS bound zinc with apparent Kd (5 +/- 2) x 10^-7 M at pH 7.5; binding was undetectable below pH 6 in this assay.
