Fucosidosis is unique among congenital exoglycosidase deficiencies, because not only oligosaccharides but large amount of glycopeptides are excreted in the urine. The structures of 22 major glycopeptides isolated from urine of a fucosidosis patient were determined. One of the prominent features common to all these glycopeptides was that they all contain 1(More)
Sialic acids (Sias) are often conjugated to the termini of cellular glycans and are key mediators of cellular recognition. Sias are nine-carbon acidic sugars, and, in vertebrates, the major species are N-acetylneuraminic acid (Neu5Ac) and N-glycolylneuraminic acid (Neu5Gc), differing in structure at the C5 position. Previously, we described a positive(More)
