The Structural Elucidation of Glycosaminoglycans [PDF]

, 2008
There is accumulating evidence of the importance of linear polysaccharides in modulating biological phenomena in both the normal and the diseased states. This layer of regulation results from interactions between polysaccharides and other biomolecules, such as proteins, at the cell-extracellular matrix interface.

Identifying metabolites by integrating metabolome databases with mass spectrometry cheminformatics. [PDF]

, 2018
Novel metabolites distinct from canonical pathways can be identified through the integration of three cheminformatics tools: BinVestigate, which queries the BinBase gas chromatography-mass spectrometry (GC-MS) metabolome database to match unknowns with ...
