What is MDL Chime?
MDL Chime is a free program that adds a specific functionality to certain browsers; namely, Chime adds the capability of interpreting 3D molecular data. The data are in the form of x, y, z coordinates, which dictate the position of every atom seen in the structure. Data files for thousands of molecular structures are freely available on the Internet at the Protein Data Bank, a searchable national database of biomolecular structures.
