Copolymers of chondroitin 4-sulfate and chondroitin 6-sulfate in chick embryo epiphyses and other cartilage.
Tetrasaccharides were prepared from chondroitin sulfate by means of a limited degradation with chondroitinase ABC. Tetrasaccharides containing one sulfate per disaccharide unit were isolated and were found to be of three types: a tetrasaccharide with two 6-sulfated disaccharide units, a tetrasaccharide with two 4-sulfated disaccharide units, and a tetrasaccharide with one 4-sulfated disaccharid...
متن کاملChondroitin sulfate concentration and protein-polysaccharide composition of articular cartilage in osteoarthritis.
In osteoarthritis the articular cartilage becomes roughened, fibrillar, softened, thinned, and finally eroded, with secondary changes occurring in the underlying bone. Histologically, early cartilage lesions in osteoarthritis are characterized by loss of metachromasia in the matrix, and it has been postulated that the initial disturbance involves the intercellular substance (1, 2). The decrease...
متن کاملZonal distribution of chondroitin-4-sulphate/dermatan sulphate and chondroitin-6-sulphate in normal and diseased human synovium.
OBJECTIVES Chondroitin sulphate is the major sulphated glycosaminoglycan present in the extracellular matrix of soft connective tissues and the aim of this study was to investigate the distribution of chondroitin sulphate species in normal and diseased synovium. METHODS Distribution of chondroitin-4-sulphate/dermatan sulphate (Ch4S/DS) and chondroitin-6-sulphate in normal (n = 6), osteoarthri...
متن کاملComparative biochemistry of chondroitin sulphate-proteins of cartilage and notochord.
Fragments that consisted mainly of two polysaccharide chains joined by a short polypeptide bridge (doublets) were prepared from chondroitin sulphate-proteins of lamprey, sturgeon, elasmobranch and ox connective tissues after hydrolysis with trypsin and chymotrypsin. Consideration of molecular parameters, compositions and behaviour on gel electrophoresis and density-gradient fractionation leads ...
متن کاملAge-related changes in the sulphation of the chondroitin sulphate linkage region from human articular cartilage aggrecan.
The chondroitin sulphate (CS) linkage regions have been isolated from human articular cartilage aggrecan (from 10- to 72-year-olds) by chondroitin ABC endolyase digestion and size-exclusion chromatography. Linkage region hexasaccharides have been characterized and their abundance estimated by high-pH anion-exchange chromatography. The basic structure for the CS linkage region oligosaccharides i...
