title: Some examples of the functions of metal ions in biology.
abstract: The ways in which certain inorganic elements are used in essential roles within biological systems generally are described. The two roles stressed are (1) electrolytic charge movements and (2) electronic charge movement. The value of helical proteins inside and outside membranes as mechanical coupling devices is analysed.
