By heating the pyridinium salts of chondroitin 4- and 6-sulfates in dimethyl sulfoxide containing 10% of water or methanol at 80 degrees C for 1--5 h, several chondroitin preparations with sulfur contents of 0.02--1.05% were prepared in 83--96% yields, respectively.

Sequential synthesis of chondroitin oligosaccharides by immobilized chondroitin polymerase mutants
Glycoconjugate Journal, 2008Escherichia coli strain K4 expresses a chondroitin (CH)-polymerizing enzyme (K4CP) that contains two glycosyltransferase active domains. K4CP alternately transfers glucuronic acid (GlcA) and N-acetyl-galactosamine (GalNAc) residues using UDP-GlcA and UDP-GalNAc donors to the nonreducing end of a CH chain acceptor.

Biosynthesis of Chondroitin Sulphates
Nature, 1959LITTLE information is available regarding the biosynthesis of acid mucopolysaccharides. Knowledge of biosynthetic pathways to the chondroitin sulphates in particular is practically confined to the fact that glucose is utilized for both the hexosamine and uronic acid moieties1 and that 3′—phosphoadenosine 5′—phosphosulphate (PAPS) is involved in ...

Monoclonal antibodies have been developed that recognize epitopes in native chondroitin sulfate chains. One of these antibodies, CS-56, reportedly recognizes chondroitin 4- and 6-sulfates. However, this antibody, and four other anti-chondroitin sulfate antibodies, 4C3, 4D3, 6C3 and 7D4, do not recognize epitopes in chondroitin sulfate chains from Swarm

Chondroitin sulfate (CS) is a structurally complex polyanionic glycosaminoglycan that plays essential roles in physiological processes. Here we report a facile approach to a library of CS tetra- and hexasaccharides based on the enzymatic degradation of chondroitin over 10 or 11 steps, which is the shortest synthetic route toward size-defined CS ...

Chondroitin, chondroitin 6-sulphate, chondroitin 4-sulphate and dermatan sulphate proteoglycans were immunolocalized by monoclonal antibodies applied to human muscle sections digested with chondroitinase. In normal muscle the 4 proteoglycans presented a different extracellular localization: unsulphated chondroitin sulphate (chondroitin) was present in ...
