BRENDA is the primary collection of enzyme functional data available to the scientific community. It is available free of charge for academic, non-profit users via the internet. Covers a wide range of enzyme characteristics. More than 50 fields containing close to half a million entries can be queried in various combinations.
This free resource (requires registration) can be used to search for the physical property data of compounds. It can be explored by chemical names, CAS registry numbers, molecular weight, and structures.
The database contains over 380,000 chemical records, of which over 269,000 include chemical structures, and is searchable by Name, Synonym, CAS Registry Number, Molecular Formula, Classification Code, Locator Code, Structure, and/or Biological/Chemical properties.
PubChem is world's largest collection of freely accessible chemical information. Search chemicals by name, molecular formula, structure, and other identifiers. Find chemical and physical properties, biological activities, safety and toxicity information, patents, literature citations and more.
HyperChem is a versatile molecular modeler and editor as well as a powerful computational package, offering many types of molecular and quantum mechanics calculations. HyperChem is accessible at the computer terminals in the Blommer Science Library and from the All Programs menu in UIS labs.
The downloadable step-by-step guide which includes screen shots (above), shows how to draw molecules and obtain the bond lengths and angles.

WebCSD is an online portal to the Cambridge Structural Database (CSD).which contains bibliographic, chemical and crystallographic information for organic molecules and metal-organic compounds whose 3D structures have been determined using X-ray diffraction or neutron diffraction.
Repository of information relative to the nomenclature of enzymes. It is primarily based on the recommendations of the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (IUBMB) and it describes each type of characterized enzyme for which an EC (Enzyme Commission) number has been provided.
