III. Polypeptide Chains Carrying More Than One Type of Carbohydrate-peptide Linkage... 

Collagen and basement membrane may contain several types of carbohydrate-peptide linkage. They clearly contain linkages in which 5-hydroxy-L-lysine is involved, as already discussed (see p. 436). From the preparations studied were also isolated glycopep-tides in which an asparagine-2-acetamido-2-deoxy-D-glucose linking moiety was present.1Bl-200... 

In dermatan sulfate from shark skin, there is about a 40% excess of sulfate groups over 2-acetamido-2-deoxy-D-galactose residues.300 The small proportions of D-glucu-ronic acid (d-GUA) present in dermatan sulfate occur in regions of the carbohydrate chains both near to, and far from, the carbohydrate-peptide linkage region. The isolation of the tetrasaccharide...
