general and specific compounds
- Cazy, Carbohydrate-Active enZymes
The CAZy database describes the families of structurally-related catalytic and carbohydrate-binding modules (or functional domains) of enzymes that degrade, modify, or create glycosidic bonds. - ChemDB
Includes many different ways to search compounds
- ChemSpider (ChemZoo)
ChemSpider is a chemistry search engine built with the intention of aggregating and indexing chemical structures and their associated information into a single searchable repository and make it available to everybody, at no charge.
