Zusammenfassung:
The structure of the oligosaccharide units of the glycoproteins of Mr 36,000 and 62,000 isolated from alveoli of patients with alveolar proteinosis have been determined by one- and two-dimensional 1H NMR spectroscopy at 500 and 360 MHz. Bi-, tri-, and tetraantennary glycans of N-acetyllactosaminic type have been found in high percentage. They are 1----6 monofucosylated and fully sialylated, the ratio NeuAc(2----3)/NeuAc X (2----6) increasing with increasing degree of branching.
