Study of the carbohydrate moiety of human serum sex hormone-binding globulin.
Sex hormone-binding globulin from human blood serum contains two biantennary N-linked oligosaccharide chains of the N-acetyllactosamine type and one O-linked oligosaccharide per one molecule of the glycoprotein. These conclusions have been based on the results of methylation analysis of the whole glycoprotein and investigation of the structures of its glycopeptides prepared using pronase digestion.
