168,812 In contrast, metal dissociation rates into solvent for those weaker binding metals, including Mn II and Fe II on the left side of this series (Figure 7), can be sufficiently rapid to be captured by both metal-buffering small molecules and ultimately the recipient acceptor protein, particularly if an open or solvent-accessible coordination site is available on the metal bound to the donor protein
The concentrations of ascorbic acid in the brain are similar to those of GSH (about 12 mM) [127], but the reactivity of ascorbic acid to ONOO is too low to provide neuroprotection [128]
Moreover, a similar experiment, but conducted ex vivo on rat liver, showed that after 18 h of fasting, the concentration of AST and ALT, as well as other cytolysis markers, increased 41
As a result, this pairing often works better than either alone
