[Keto sugars in the urine of patients with chronic pancreatitis]

Simultaneously with fructose and sucrose, five oligosaccharides, containing fructose residue and exhibiting reducing properties, were found in urine of patients with chronic pancreatitis and with liver impairments caused by ethanol intoxication. Four of the oligosaccharides were trisaccharides, containing fructose residue and two residues of glucose as well as one tetrassaccharide, comprizing a residue of fructose and three residues of glucose. The fructose residue occupied the terminal position in all the oligosaccharides. The oligosaccharides found in urine of the patients were dissimilar in the types of link between residues of glucose and between residues of fructose and glucose; these oligosaccharides exhibited different chromatographic mobility.
