[The structure of carbohydrate chains of riboflavin-binding glycoprotein from chicken egg protein. III. 1H-NMR spectroscopy (500 MHz) of neutral fucosylated oligosaccharides].

Using LiBH4/ButOH treatment, oligosaccharides were cleaved off the hen egg white riboflavin-binding glycoprotein. HPLC led to the isolation of four fucose-containing oligosaccharide alditols, whose structure was elucidated by means of 1H NMR 500 MHz spectroscopy. The main fucosylated oligosaccharide, also present in hen ovomucoid, was found to be a biantennary carbohydrate chain of N-acetyllactosamine type.
