  • Title: Heterogeneity of rat rib chondroitin sulfate and susceptibility to rat gastric chondrosulfatase.
    Author: Liau YH, Galicki NI, Horowitz MI.
    Journal: Biochim Biophys Acta; 1978 Mar 20; 539(3):315-23. PubMed ID: 630005.
    Abstract:
    Cartilage chondroitin sulfate isolated directly from rat rib or from in vitro culture of rat rib constitutes a population of glycosaminoglycans which is heterogeneous with respect to size, degree of sulfation and content of N-acetyl-galactosamine 4-sulfate. Fractions, elute from Dowex-1 in order of increasing molecular size and degree of sulfation up to a certain limit. Unsulfated disaccharides and disulfated disaccharides are present in both the undersulfated chondroitin sulfate fractions and in the average or more representative chondroitin sulfate. A small content of disccharide 6-sulfate is present in all fractions and appears to be an integral part of the chondroitin 4-sulfate molecules. Rat gastric chondrosulfatase hydrolyzes sulfate preferentially from the larger chondroitin 4-sulfate molecules, and the sulfate is removed primarily from the disaccharide 4-sulfate units.
