The important elements in biology
Patricia C. Wilkins, Ralph G. Wilkins
Inorganic Chemistry in Biology
Abstract
This chapter talks about essential elements which are derived from the s-, p-, and d-blocks and analyses the different general functions of each block. It discusses the vital role played by elements other than carbon for specific functions and emphasizes a fine balance between a deficiency, an excess intake, and a short range of daily intake that is essential and optimal. It also outlines the importance of organic compounds in the functioning of the human body. It mentions elements that have become of marked clinical value. The chapter analyses highly toxic elements, such as soft cations that bind sulfur ligands and S-containing amino acids. It points out that all toxic elements are chemically similar to an essential element.
