Glycosaminoglycans (GAGs) are richly represented components of connective tissue, matrix which plays an important role in the functioning of tissues. These compounds belong to the group heteropolysaccharides, and they occur as long chains of repeated disaccharide units, consisting of amino sugar and uronic acid. Most of GAGs form covalent bonds with proteins to produce proteoglycans in effect. Because of the presence of a large number of ?OH groups and negative charge, GAGs are capable of binding great numbers of water molecules inducing the effect of swelling. For this reason GAGs are widely used cosmetic ingredients responsible for moisturizing effect, while contributing to the improvement of skin firmness and elasticity.
