Small Molecule Databases

Many public databases are available with information on proteins, small molecules, RNA, cells, and more. Many datasets are aggregates of other datasets and therefore overlap between databases can be high. While some datasets are extensively curated by hand, most are automated and therefore redundancy within a dataset can also be high.
