- Atoms, Bonding and Structure: Topics include: chemical elements, compounds
and mixtures; atomic structure; chemical bonding; structure of materials and bond energies. Includes interactive simulations of ionic
bonding and covalent bonding.
- BodyQuest: Bodyquest is an exploration of anatomy designed for students aged between 11 and 16.
- Cell Biology: The following list of sites display web pages written by Gwen V. Childs, Ph.D. while she was Professor and Vice-Chair, Department of Anatomy and Neurosciences. They were originally for use by graduate and medical students at the University of Texas Medical Branch in Galveston, TX. Dr. Childs now is at the University of Arkansas for Medical Sciences, in Little Rock, AR.
The following web pages served as study guides and handouts for lectures in Cell Biology. Each was designed to introduce the topic and provide structure/function correlations. The guides are not intended to be a complete presentation of all of the material in that subject area since each unit was team taught and Dr. Childs provided the introductory material that correlated structure and function. The guides provide illustrations missing in the assigned text. The web pages also provide questions that students can use to test their knowledge as they learn the material. Use the following menu, or scroll down to click on regions in the photograph image maps that show the organelle of interest.
- Deep View SPDB viewer: Swiss-PdbViewer is an application that provides a user friendly interface allowing to analyse several proteins at the same time. The
proteins can be superimposed in order to deduce structural alignments and compare their active sites or any other relevant parts. Amino
acid mutations, H-bonds, angles and distances between atoms are easy to obtain thanks to the intuitive graphic and menu interface.
- Human Anatomy Online: Welcome to Human Anatomy On-line the place for fun, interactive and educational views of the human body.
- Pauling, Linus Carl: The subjects of the papers he published reflect his great scientific versatility: about 350 publications in the fields of experimental
determination of the structure of crystals by the diffraction of X-rays and the interpretation of these structures in terms of the radii
and other properties of atoms;
- Protein Architecture tutorials: The Lehninger 3D Structure Tutorials are designed to accompany Principles of
Biochemistry, 3rd edition, by Lehninger, Nelson, and Cox. They are built around the Chemscape Chime 2.0
plugin, which reads the atomic coordinates of a biological macromolecule and renders it as a fully interactive
Learn about all aspects of
protein structure, from the chemical
properties of the amino acids to the

- SCORPION (amino acid frequences): SCORPION is the WWW tool for analysis of the amino acid frequences within
protein chain(s) (of given pdb file or group of pdb files) as well as foranalysis of
3D contacts of C-alpha and/or Last Hevy Atoms in the residue side chain (LHA).
Convinient Graphical presentation can be used for identification of specific
interactions for given family of the proteins or given domains.
- Swiss PDB Viewer: Swiss-PdbViewer is an application that provides a user friendly interface allowing to analyse several proteins at the
same time. The proteins can be superimposed in order to deduce structural alignments and compare their active sites
or any other relevant parts. Amino acid mutations, H-bonds, angles and distances between atoms are easy to obtain
thanks to the intuitive graphic and menu interface.
Moreover, Swiss-PdbViewer is tightly linked to Swiss-Model, an automated homology modelling server running at Glaxo
Welcome Experimental Research in Geneva.
- The Basics of NMR: Nuclear magnetic resonance, or NMR as it is abbreviated by scientists, is a phenomenon which occurs when the nuclei of certain atoms are immersed in a static magnetic field and exposed to a second oscillating magnetic field.
- The Periodic table of comics books: The Web site shows a Periodic Table of the Elements (a systematic arrangement of all the known chemical
elements according to their atomic structure) and comic books that featured those elements, both in their
characters and plots.
