Abstract A glycopeptide was isolated from normal human urine by fractionation on a column of Sephadex G-10 and preparative ion-exchange chromatography. Elution behavior during ion-exchange chromatography in two different solvent systems, amino acids formed upon hydrolysis, and migration on high-voltage electrophoresis and thin-layer chromatography were essentially identical for this substance and for authentic 2-acetamido-l-β-(L-β-aspartamido)-1,2-dideoxy-D-glucose. A technique was developed to permit analytical-scale fractionation of individual urines followed by analysis for this glycopeptide; urine from two normal individuals contained 7 and 11 µmol of 2-acetamido-1-β-(L-β-aspartamido)-1,2-dideoxy-D-glucose per liter.
