| Since cell walls contain high concentrations of uronic acids, cations are accumulated within cell walls while mobile anions are excluded. |
| The channel is impermeable to anions but is permeable to a diverse group of cations. |
| Xanthate anions and protonated xanthic acid contain a free thiol moiety and are highly reductive. |
| The administration of superoxide dismutase to scavenge superoxide anions was found to promote the survival rate of transplanted skin flaps. |
| As a result, carbonyl compounds can form carbon anions and act as nucleophiles rather than electrophiles. |
| In solution, the cations move towards the cathode and the anions move to the anode. |
