Full-text journals for life and health sciences from 1995-present.  Includes abstracts for other scientific information.

Full-text collection of journals in business, humanities, social sciences, science, technology, and medicine.

Contains substance information electronically submitted to PubChem by depositors.  This includes any chemical structure information submitted, as well as chemical names, comments, and links to the depositor's web site.

Contains unique, validated chemical structures (small molecules) that can be searched using names, synonyms or keywords. The compound records may link to more than one PubChem Substance record if different depositors supplied the same structure. These Compound records reflect validated chemical depiction information provided to describe substances in PubChem Substance. Structures stored within PubChem Compounds are pre-clustered and cross-referenced by identity and similarity groups.

Consists of deposited bioactivity data and descriptions of bioactivity assays used to screen the chemical substances contained in the PubChem Substance database, including descriptions of the conditions and the readouts (bioactivity levels) specific to the screening procedure.

Pathways involve the interactions between chemicals, proteins, and genes. This integration helps to improve access to and highlight available pathway resources as well as to provide a context for a given chemical or target.
