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.
