title: [Isolation and characteristics of carbohydrate chains of riboflavin-binding glycoprotein from the chicken egg].
abstract: Isolation and characterization of oligosaccharides of riboflavin binding glycoprotein from hen white is described. Reductive cleavage of the N-glycosylamide carbohydrate-peptide bond with LiBH4/tert-BuOH followed by NaBH4-NaOH treatment gave rise to alditols, which were fractionated by means of HPLC. Twelve alditols were isolated in quantities sufficient for the monosaccharide analysis. Possibility of an ovomucoid-type oligosaccharide structure for all the alditols is discussed.
