The objective was the development of the Complex Carbohydrate Structural Database (CCSD) and the database management program CarbBank which will give systematic access to published carbohydrate structures. Collection of structural data is performed manually by a systematic survey of the existing carbohydrate literature, relevant citations are obtained by computer assisted searching on the Chemical Abstract CAS ONLINE service and other important data (for example a compressed structural formula, optical rotation, nuclear magnetic resonance data, melting point) are added manually. The first version of the CCSD and CarbBank released in October 1989 has been revised and updated, the latest version (December 1990) now contains 3888 complex carbohydrate structures. A contract has been negotiated between the European partners, the American collaborators in Georgia and Chemical Abstract services, which has resulted in free exchange of data and thereby securing a much more complete database.
Correlation of structures with Nuclear Magnetic Resonance Spectroscopic data has been facilitated by creating a computer program, which allows easy connection between structure and data. The program is available as a test version.
