title: Identification of trisaccharide Xyl alpha 1-->3Xyl alpha 1-->3Glc in human urine.
abstract: Oligosaccharides in human urine were converted to pyridylamino (PA)-derivatives. From the PA-oligosaccharides, a saccharide that was chromatographically identical with a synthetic standard, Xyl-alpha 1-->3Xyl alpha 1-->3Glc-PA, was isolated by gel filtration and HPLC. Structure analysis showed that the saccharide was Xyl alpha 1-->3Xyl-alpha 1-->3Glc-PA. It is likely that Xyl alpha 1-->3Xyl alpha 1-->3Glc originated from such glycoconjugates as blood coagulation factors VII and IX, and protein Z.
