General description

Chondroitin, a glucosaminoglycan (GAG), is a polysaccharide chain of alternating units of N-acetylgalactosamine (GalNAc) and glucuronic acid (GlcA) that can be sulfated on the either or both GalNAc and GlcA units. Chondroitin and its sulfates are frequently attached to proteins to form proteoglycans.

Application

Chondroitin disaccharide Δdi-4S may be used as a substrate for the identification and characterization of enzymes such as Clostridium perfringens unsaturated glucuronyl hydrolase. Chondroitin disaccharide Δdi-4S may be used as a reference compound in the analysis of chondroitin disaccharide sulfates.

Other Notes

ΔUA = 4-deoxy-L-threo-hex-4-enopyranosyluronic acid; GalNAc = N-acetyl-D-galactosamine; 4S = 4-sulfate
