Glycosaminoglycan
Glycosaminoglycans (GAGs) are long, unbranched carbohydrates made up of repeating disaccharide units. They are an essential component of the extracellular matrix, providing structural support and influencing cell behavior. GAGs are found in various tissues, including cartilage, skin, and blood vessels, and play a crucial role in maintaining hydration and elasticity.
Common types of GAGs include hyaluronic acid, chondroitin sulfate, and heparin. These molecules are involved in various biological processes, such as cell signaling, wound healing, and inflammation. Due to their unique properties, GAGs are also used in medical and cosmetic applications, including joint health supplements and skincare products.
