PubChem

Pubchem contains 3 databases. 1. PubChem BioAssay: The PubChem BioAssay Database contains bioactivity screens of chemical substances described in PubChem Substance. It provides searchable descriptions of each bioassay, including descriptions of the conditions and readouts specific to that screening procedure. 2. PubChem Compound: The PubChem Compound Database contains 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. 3. PubChem Substance. The PubChem Substance Database contains descriptions of samples, from a variety of sources, and links to biological screening results that are available in PubChem BioAssay. If the chemical contents of a sample are known, the description includes links to PubChem Compound.

PubChem数据库共包含三个数据库。1. PubChem生物活性测试库：该数据库收录了PubChem物质库中描述的化学物质的生物活性筛选信息。它提供了每个生物活性的可搜索描述，包括特定筛选程序的条件和读数描述。2. PubChem化合物库：该数据库包含了用于描述PubChem物质库中物质的经验证的化学描述信息。存储在PubChem化合物中的结构已根据身份和相似性组进行预聚类和交叉引用。3. PubChem物质库：该数据库包含了来自各种来源的样本描述，以及指向PubChem生物活性测试库中可用的生物筛选结果的链接。如果已知样本的化学成分，描述中还包括了指向PubChem化合物库的链接。
