摘要：

A sialic acid-rich (30%) sialoglycopeptide, soluble in 50% ethanol, has been obtained in a homogeneous form, by gel filtration and cellulose chromatography. It contains: hexoses (chiefly galactose, but also mannose and glucose) 18.4%; hexosamines (glucosamine and galactosamine) 17%; and fucose 5.7%. Only one neuraminic acid derivative has been identified, the (N-acetylneuraminic acid. The peptide moiety contains; aspartic acid, serine, threonine, glutamic acid, proline, glycine and alanine. The origin of the urinary glycopeptides is discussed. © 1969.
