Atomic Weights of the elements, 2007 

Published by IUPAC’s Commission on Atomic Weights and Isotopic Abundances.


Biomolecular Object Network Databank (BOND) 

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 

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.

 

American Chemical Society 

Primary professional organization for chemists and related occupations.

 

Directory of Graduate Research 

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.

 

Links for Chemists 

Index to chemistry links on the Web: publications, organizations, databases, topic categories, etc. Part of the WWW Virtual Library project.

 

NIST Chemistry Webbook 

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.

 

Map of the Nuclides 

Isotopic map depicting elemental decay schemes and energy levels.

 

PubChem 

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 

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 

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 

Links to chemistry sites, including conversion tables, periodic tables, scientific constants and the structure of amino acids.
