  • Title: Characterization of dermatan sulfate and heparan sulfate in the urine of a patient with the Hunter syndrome.
    Author: Kimura A, Hayashi S, Tsurumi K.
    Journal: Tohoku J Exp Med; 1980 Jul; 131(3):227-39. PubMed ID: 6447930.
    Abstract:
    Glycosaminoglycan isolated from the urine of a patient with the Hunter syndrome was composed of heparan sulfate (59.9%), dermatan sulfate (30.6%) and chondroitin sulfate (9.5%), and was heterogeneous in molecular weight (1,500-10,000) and in sulfate content (0.35-2.05 moles/mole of hexosamine). About 60% of dermatan sulfate and 10% of heparan sulfate had molecular weight of 7,000 to 10,000, while about 10% of the former and 60% of the latter had those of 1,500 to 3,500. Sulfate contents of dermatan sulfate and heparan sulfate were inversely related to their molecular weights. Higher total- and N-sulfate contents were measured in smaller molecular-weight heparan sulfate, and higher acetyl content was in larger molecular-weight heparan sulfate. On the basis of the chemical properties of dermatan sulfate and heparan sulfate isolated in this experiment, their catabolic processes in the Hunter syndrome were discussed.
