Intestinal Absorption of Metal Ions, Trace Elements, and Radionuclides focuses on the transport of metal ions across biological membranes. The selection first discusses fundamental considerations of ion transport across biological membranes, including passage of ions through the pores of gels or membranes; mobilities of organic and inorganic ions in water; and complexing of alkali metal ions. The text then focuses on ion transport across membranes of high ionic selectivity and transmissivity and their uses in model studies; model systems for transcellular active transport; and detection and implications of active salt transport across biological membranes. The book takes a look at the intestinal absorption of sodium, calcium, and potassium, including sodium and potassium transport in the intestines; use of radioisotopes to assess intestinal flux of calcium in humans; and calcium and structure of cell membranes. The intestinal absorption of zinc, cobalt, and strontium and absorption of copper from the gastrointestinal tract are underscored. The selection is a recommendable source of data for readers interested in the transport of metal ions across biological membranes.
