Intestinal Absorption of Metal Ions, Trace Elements and …

Intestinal Absorption of Metal Ions, Trace Elements, and Radionuclides focuses on the transport of metal ions across biological meranes. The selection first discusses fundamental considerations of ion transport across biological meranes, including passage of ions through the pores of gels or meranes; mobilities of organic and inorganic ions in water; and complexing of alkali metal ions.
