These strategies are 1) cell surface display of metal-binding and nucleating peptides, 2) engineered metal transporters for metal uptake, and 3) engineered metabolic pathways that preferentially react with, or reduce, heavy metals.
The results showed that Fe3+ ions would preferentially react with OH- ions in solution.
In addition, in the presence of high concentration of peroxide, OH· radicals preferentially react with the excess of H2O2.
They preferentially react with flexible nucleotides but poorly with base-pared and protected nucleotides.
As indicated above, soft electrophiles such as ACR preferentially react with soft nucleophiles.
In contrast, α,β-unsaturated carbonyl derivatives, alkenals, and the α-oxoaldehydes are soft electrophiles that preferentially react with soft nucleophilic thiolate groups on cysteine residues.
Further, preferred chemical reactivity of the PIC group may not bias the outcome of a PIC experiment, and in some cases, such reactivity may even be desired (e.g., where a binding site contains an amino acid with which the PIC group preferentially reacts).
Vinyl silane group preferentially reacted with hydride silane, resulting in the formation of AB2 type intermediates containing one hydride silane and two acrylate (or methacrylate) groups, at the same time, there may be low quantity of B4 type intermediates.
The rate at which hydrogen oxidizes is significantly faster than that of carbon, thus hydrogen preferentially reacts with the available oxygen in the mixture.
In mixtures of metallic and semiconducting carbon nanotubes, diazonium preferentially reacts only with the metallic tubes, allowing their identification and separation.
