Biomolecular
Interaction Network Database (BIND)(http://bind.ca/)
A collection of records documenting molecular interactions compiled
from high-throughput data submissions and hand-curated information
from the scientific literature. An interactive database allows searching
based on interactions, molecular complexes, and pathways.
Biocyc(http://biocyc.org/intro.shtml)
A powerful tool to visualize the layout of genes within a chromosome,
or of an individual biochemical reaction, or of a complete biochemical
pathway. Browse by pathway, gene, reactions, and compounds. Detailed
organism-specific databases are available for 14 species.
Chemistry.org(http://www.acs.org/)
Offers news, education and tools for every type of user (professional,
educator and student, enthusiast). A service of the American Chemical
Society.
Directory of Graduate Research(http://dgr.rints.com/)
The Directory of Graduate Research (DGR), published by the American Chemical
Society is a complete source of information on chemical research and researchers
at universities in the United States and Canada.

Index to chemistry links on the Web: publications, organizations,
databases, topic categories, etc. Part of the WWW Virtual Library
project.
NIST
Chemistry Webbook(http://Webbook.nist.gov/chemistry/)
Thermochemical, thermophysical and ion energetics data compiled
by NIST, specifically data on gas phase thermochemistry, condensed
phase thermodynamics, phase changes, reaction thermodynamics, gas
phase ion energetics, infrared spectra and mass spectra.

Isotopic map depicting elemental decay schemes and energy levels.
PubChem(http://pubchem.ncbi.nlm.nih.gov/)
PubChem is NIH's Small Molecule Repository. PubChem includes substance
information, compound structures, and bioactivity data. The database
may be searched on the basis of descriptive terms, chemical properties,
and structural similarity. When possible, PubChem's chemical structure
records are linked to other NCBI databases (e.g., PubMed, protein
3D structure, etc.)
STITCH: Chemical-Protein Interactions(http://stitch.embl.de/)
STITCH (Search Tool for Interactions of Chemicals') integrates information about interactions from metabolic pathways, crystal structures, binding experiments and drug-target relationships. Inferred information from phenotypic effects, text mining and chemical structure similarity is used to predict relations between chemicals. Each proposed interaction can be traced back to the original data sources. The database contains interaction information for over 68 000 different chemicals, including 2200 drugs, and connects them to 1.5 million genes across 373 genomes and their interactions contained in the STRING database.
Synthetic Pages(http://www.syntheticpages.org)
Synthetic Pages is a free database of reliable organic, organometallic and inorganic chemical synthesis, reactions and procedures deposited by synthetic chemists working in academic and industrial research laboratories. In addition to the procedures, the record also includes frequently encountered problems, trouble-shooting tips, the number of times the reaction has been carried out, scale-variation, etc.
Yahoo
Chemistry Page(http://dir.yahoo.com/science/chemistry/)
Links to chemistry sites, including conversion tables, periodic
tables, scientific constants and the structure of amino acids.
