Abstract

The oligosaccharide units of a type K and a type L IgA immunoglobulin have been examined. The two proteins differed in their content of 6-deoxy-l-galactose and N-acetylneuraminic acid, and in the d-mannose/d-galactose ratio. With glycopeptides prepared from the type K protein, specific glycosidases liberated the N-acetylneuraminic acid and 7–8 residues of 2-acetamido-2-deoxy-d-glucose, and mild acid hydrolysis released most of the 6-deoxy-l-galactose. The type K immunoglobulin appeared to contain 3 oligosaccharide units, whereas the type L protein probably contained 3 or more units.
