| This indicated that the sequestration capacity of iron plaque may be different between cations and anions. |
| Since cell walls contain high concentrations of uronic acids, cations are accumulated within cell walls while mobile anions are excluded. |
| An ionic compound is composed of a network of ions that results in a three-dimensional matrix of cations and anions. |
| The administration of superoxide dismutase to scavenge superoxide anions was found to promote the survival rate of transplanted skin flaps. |
| Subsequent oxidation-reduction reactions can also produce superoxide anions, hydrogen peroxide and hydroxyl radicals. |
| Examples of compounds or groups that accept anions include the nitrate and hydroxide radicals. |
