| Popis: | ABSTRACT: Glycosaminoglycans (GAGs) are long-chain polysaccharides that are divided into sulphates and non-sulphates, these being chondroitin sulphate, heparan sulphate, dermatan sulphate, heparin sulphate and the only non-sulphate in the group is hyaluronic acid. GAGs are obtained from animal tissue and by an expensive low-yield extraction process; however, they are highly commercially valued polysaccharides and exploited in the biomedical market. Their disaccharidic composition, chain length and sulfation pattern present great variability depending on the species and extraction factors. GAGs possess immunomodulatory, antioxidant, antiviral, anti-inflammatory, neuroprotective, antiproliferative and anticoagulant properties, functioning as therapeutic agents modulating an array of biological processes. This report presents the general aspects of each GAG, source and extraction process, in addition to the characteristics that give them the most varied therapeutic properties and pharmacological applications. |
