(a) Biosynthesis of the linker tetrasaccharide of HS and CS/DS from a xylosylated protein or an exogenously supplied xyloside with an aromatic aglycon. (b) Concept of this study: azide-functionalized xylosides that can prime GAGs and serve as tools for investigations of the biosynthesis and functions of GAGs.
