Biochemical Periodic Tables

The UM-BBD contains two different representations of the chemical periodic table of the elements (Traditional and Spiral). Each links to web pages for elements that are transformed by, bound by, or are otherwise important in, biological systems. The elements pages contain links to resources outside of the UM-BBD server. Links to WebElements and PubMed are standard. Below is a list of element pages and their non-standard external links.
