and Dean, J.F., 2001.Oxidation of phenolate
siderophores by the multicopper oxidase encoded by the Escherichia coli yacK gene.
mofetil (MMF) was initiated for the treatment of presumed vasculitis (unfortunately despite the request of the medical team no operative specimens were sent for histological analysis).
conducted microsecond flash photolysis experiments on PC and model compounds in dichloroethane solution [6, 7], Results were interpreted to be due to a Photo-Fries rearrangement occurring via an intermolecular route, resulting in free radicals arising from energy transfer between the phenolate
[pi]* state and the carbonyl group.
Uptake of PNP onto the three adsorbent may have been in the molecular form rather than the phenolate

In Figure S2, a very strong band is below 400 nm for Schiff base (303 nm) and at 344 nm for complexes, due to ligand-centered [pi] [right arrow] [[pi].sup.*]/[pi] [right arrow] [[pi].sup.*] (most probably from phenolate
oxygen donor atom) transitions (LLCT).
In TPC assay, a phenol in plant extracts loses a proton to form phenolate
ion, which reduces Folin Ciocalteu reagent, and the resulting changes are measured spectrophotometrically at 765 nm .
, the electrochemical oxidation of p-coumaric and ferulic acids involves an electron transfer from the corresponding phenolate
The fact that the overall reaction rate depends on the proportion of ionized molecules of the antioxidant (typically the phenolate
group)  implies that, apart from the structure of the antioxidant molecule, the type of solvent and the pH of the assay solution in particular have a large influence on the reactivity of antioxidants [6-10].
The ionic fraction of phenolate
ion(ion) can be calculated by the following equation.
At the same time, it is possible that the phenolic compounds have lower electron affinity towards carbon spheres in the shape of phenolate
, it is because the donoric nature of the anionic oxygen counteracts the presence of nitro attractor groups.
Humic compounds and organic acids, which are contained in compost, are contain functional groups that have negative charged, such as: -COOH, -OH phenolate
, and -OH alcoholate , so that they can bind cations, such as A1 and Fe.
