Glycosaminoglycans

Glycosaminoglycans (GAGs) are a group of complex carbohydrates found in the extracellular matrix of animal cells. They are key components of the extracellular matrix and involved in a variety of biological processes, such as cell adhesion, cell differentiation and growth regulation. They are important in the formation of connective tissue, which provides stability and strength to the body's tissues. GAGs also play a role in the regulation of the immune system and in the maintenance of healthy joints. The most common GAGs are the hyaluronan, chondroitin sulfate, heparin and dermatan sulfate. They are also used in drug delivery systems and medical therapies, including wound healing, cartilage repair and pain management. In addition, GAGs are also used in cosmetic products, such as skin moisturizers and anti-aging creams.
