Heteropolysaccharides, formally defined as glycosaminoglycans (GAGs), constitute a class of structural mucopolysaccharides composed of modified sugar derivatives such as glucosamine and galactosamine alongside uronic acids. These macromolecules are characterized by the presence of acidic functional groups like sulfate and carboxyl moieties, which confer negative charges essential for their roles in tissue architecture and biochemical interactions within connective tissues. As primary constituents of extracellular matrix ground substances like proteoglycans and mucoproteins, GAGs determine tissue viscoelasticity, lubrication, hydration status, and shape maintenance across biological systems ranging from cartilage to blood vessels.
