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.

Synthesis and Structure Elucidation of Glutamyl-Queuosine. [PDF]
J Am Chem Soc, 2023 Queuosine is one of the most complex hypermodified RNA nucleosides found in the Wobble position of tRNAs. In addition to Queuosine itself, several further modified derivatives are known, where the cyclopentene ring structure is additionally modified by a galactosyl-, a mannosyl-, or a glutamyl-residue.
