Low-energy configurations for atomic and molecular clusters bound by various potential energy functions. Images and Cartesian coordinates are supplied.

QuickTime versions of molecular animation sequences from the late 1960s and early 1970s, with an emphasis on biomacromolecules.

This site uses kinemages to highlight the structural features of FGF ligands and receptors. Java-enabled browsers can manipulate the structures in real time using the KiNG application.

Pictures of the molecular structure of amino acids. Also features common properties of all amino acids, peptide structures, and a protein structure quiz.

Three-dimensional images and structures (in Protein Data Bank format) of molecules, sorted by name, empirical formula, and organic functional group. Listing by empirical formula also includes information on a compound's industrial and pharmaceutical uses.

PDB provides a text based format for archiving experimentally-determined, three dimensional structures, at the Brookhaven National Laboratory, with list of mirror sites worldwide.
