(GAGs) - large to huge molecules of the connective tissue matrix, made up of repeating disaccharide units linked to a protein core. The disaccharide units are made of glucosamine and glucuronic acid. The position of a sulphate molecule on the glucosamine determines the type of GAG.

Heteropolysaccharides which contain an n-acetylated hexosamine in a characteristic repeating disaccharide unit. The repeating structure of each disaccharide involves alternate 1,4- and 1,3-linkages consisting of either n-acetylglucosamine or n-acetylgalactosamine. ... (12 Dec 1998) ...

(= formerly mucopolysaccharides) Polysaccharide side-chains of proteoglycans made up of repeating disaccharide units (more than 100) of amino sugars, at least one of which has a negatively charged side-group (carboxylate or sulphate). Commonest are hyaluronate (D-glucuronic acid- N-acetyl-D-glucosamine: MW up to 10 million), chondroitin sulphate (D-glucuronic acid- N-acetyl-D-galactosamine-4 or -6-sulphate), dermatan sulphate (D-glucuronic acid- or L-iduronic acid- N-acetyl-D-galactosamine), keratan sulphate (D-galactose- N-acetyl-D-glucosamine-sulphate), and heparan sulphate (D-glucuronic acid- or L-iduronic acid- N-acetyl-D-glucosamine). Glycosaminoglycan side chains (with the exception of hyaluronate) are covalently attached to a core protein at about every 12 amino acid residues to produce a proteoglycan; these proteoglycans are then non-covalently attached by link proteins to hyaluronate, forming an enormous hydrated space-filling polymer found in extracellular matrix. The extent of sulphation is variable and the structure allows tremendous diversity.
