Characterization of beta-D-xyloside-initiated glycosaminoglycan synthesized by human skin fibroblasts in the presence of tunicamycin.

abstract：:Two azidohexasaccharide building blocks, of which the glycosyl acceptor was the 5-(methoxycarbonyl)pentyl glycoside, were coupled using the trichloroacetimidate technology. The 12 azido functions present in the dodecasaccharide thus formed were then converted to amino groups using hydrogen sulfide as a reducing reagen...
