We are actively working on improving the ADAP-KDB website and adding new features and updates every Sunday, 1pm - 11pm GMT. You may experience interruptions in the website work during that period.

Welcome to ADAP-KDB Spectral Knowledgebase!

ADAP-KDB Spectral Knowledgebase
Analytical Chemistry

The number of metabolomics studies in public data repositories such as the NIH’s Metabolomics Data Repository (a.k.a. Metabolomics Workbench) and MetaboLights acquiring untargeted data from the liquid chromatography (LC-) and gas chromatography coupled to mass spectrometry (GC-MS) analytical platforms has been steadily growing. Accompanying this growth is the enormous number of known and unknown compounds contained in that data, providing an invaluable opportunity to harness the power of big data and allow for cross-species, cross-diseases, and cross-sample source analysis.

Toward this end, we have developed ADAP-KDB, a mass spectral knowledgebase that contains consensus GC-MS and LC-MS/MS spectra constructed from untargeted, publicly available metabolomics data. At this point, all the consensus spectra are constructed from data in the Metabolomics Workbench and spectra constructed similarly from other publicly available data repositories will be gradually added.

ADAP-KDB enables efficient sharing and aggregation of information about both known and unknown compounds across studies and laboratories and makes those compounds easily findable.
