Medical Biochemistry Page"This online textbook thoroughly presents many aspects of biochemistry, with an emphasis on clinical medicine; it features straightforward text and high-quality illustrations. The home page acts as a table of contents with 53 links to chapters on topics like Diabetes Type 1 and Type 2; the Cell Cycle; Thermodynamics Review; Protein Synthesis; and Iron, Heme, and Porphyrin Metabolism. Each category's table of contents links to segments of a virtual chapter, and navigation is easy with links like "back to top," the chapter outline, or the home page. A Google search box enables searching within the site or the Web. Original color illustrations enhance most chapters, and nearly every section has chemical formulas and illustrations of molecules' structures and interactions. The Google ads are a minor annoyance, but most computers' displays reduce their prominence for the reader. King (Indiana Univ. School of Medicine), the author of a textbook and editor of medical school entrance examination guides, is responsible for the written text and most of the illustrations and graphics on the site (which does not reference other texts or journal articles)."
