This Web site features BioMagResBank (BMRB); the free public access depository for NMR results from peptides, proteins, and nucleic acids. Biochemists can find a collection of computer software applications used for biomolecular NMR such as Aqua and NMRView, as well as a Library of NMR Software. The website provides NMR data file conversion tools including the STAR conversion handling tool, which...

The Cytokines Online Pathfinder Encyclopaedia (COPE) is the brainchild of Horst Ibelgaufts of Germany's Ludwig-Maximilians-Universit't Gene Center. Part super-glossary, part general guide to the "jungles, morasses, and deserts of cytokine-land," this incredibly extensive Web site helps researchers stay on top of newly identified proteins and previously identified but recently reevaluated proteins....

The Institute for Molecular Biotechnology (Jena, Germany) provides this repository of molecular structures, featuring selected VRML (as well as two dimensional) images of "building blocks," and "macromolecular structures." Included among the images are RNA structures from the protein database at the Brookhaven National Laboratory, as well as over 250 DNA and protein structures. Sequence and...

The Muscle Physiology Lab at the University of California-San Diego provides this comprehensive source of information on the neuromuscular system. The Web site appears as a extensive menu of subtopics, each leading to pages of detailed text and diagrams. Students studying muscle structure and function should find this well-organized and authoritative resource extremely useful. The Web site also...

The International Union of Pure and Applied Chemistry's Joint Commission on Biochemical Nomenclature has put online the text of its nomenclatural recommendations for Tetrapyrroles. These were published in 1986 but were not posted online until this year. the text includes tables, illustrations, and notes.

Part of the Common Molecules Collection, this set of 3D biochemical molecule images is an educational feature from Reciprocal Net, a Web portal for crystallography research funded by the National Science Foundation and part of NSDL. The Common Molecules Collection currently offers a number of image galleries, but only a couple -- including the biochemical molecules set -- with direct life sciences...

This University of Arizona website provides numerous chemistry tutorials and problem sets primarily for biology students. The lessons are divided into two main categories: chemistry of life and energy reactions. Students can find clear, in-depth explanations of amino acids, pH levels, photosynthesis, metabolism, and more. Each section is filled with helpful, colorful images. The website provides...
