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 acts on it

  1. An additional m/z 401.3 ion was consistent with a 1:1 riboflavin–boric-acid complex in alkaline electrospray experiments; the ribityl binding site was not resolved.

    Nominal mass is consistent with, but does not uniquely establish, the proposed 1:1 structure. No site-resolving NMR or in-vivo binding measurement; signal intensity is not a bound fraction.

    A laboratory signal suggests boron can attach to vitamin B2; this does not prove that usual boron intake depletes B2.
