General multidisciplinary database covering virtually every subject area. Includes full-text peer-reviewed journals, magazines, newspapers, and other sources.
PubChem is an open chemistry database at the National Institutes of Health (NIH).
PubChem mostly contains small molecules, but also larger molecules such as nucleotides, carbohydrates, lipids, peptides, and chemically-modified macromolecules. We collect information on chemical structures, identifiers, chemical and physical properties, biological activities, patents, health, safety, toxicity data, and many others.
PubChem is an open archive of chemical substances and their biological experimental results. It accepts chemical structures, names, links, spectra and associated bioassay test results.
