It is also used as a source of zinc ions.

Each of these proteins is a zinc-dependent enzyme, binding 3 zinc ions per molecule.

The zinc ion is chelated by one hisitidine and three cysteine.

The coordination sphere of the zinc ion is approximately tetrahedral.

Metallothionein also carries zinc ions (signals) from one part of the cell to another.

ZnT-3 is required for the accumulation of zinc ions inside synaptic vesicles.

The free zinc ion in solution is highly toxic to plants, invertebrates, and even vertebrate fish.

The free zinc ion is a powerful Lewis acid up to the point of being corrosive.

As a low-voltage electrical charge is applied, the zinc ions cling to the plates.

The use of a zinc ion in binding leads to a higher affinity interaction.
