The Protein-Bound Carbohydrates of Seromucoid from Normal Human Serum

Summary: The neutral sugars and hcxosamines in the seromucoid fraction of normal human serum were identified and determined simultaneously by gas-liquid chromatography of their aldononitrilc acctates. Be-sidcs the sialic acid, normal seromucoid contained fucose, arabinose, mannosc, glucose, galactose, glucosam-ine and galactosamine. The presence of arabinose and glucose, not previously reported in seromucoid, äs well äs the other known carbohydrate components determined by GLC were confirmed from their fragmentation patterns in the electron impact mass spectra and chemical ionization spcctra.
