Glycosaminoglycans

Glycosaminoglycans (GAGs) are long, unbranched chains of complex sugars found in the body's connective tissues, such as cartilage, skin, and blood vessels. They play a crucial role in providing structural support, maintaining elasticity, and helping tissues retain water. GAGs also contribute to cell signaling and tissue repair. These molecules are negatively charged, allowing them to attract water and form gel-like substances that cushion and protect organs and joints. Examples include heparin, chondroitin sulfate, and hyaluronic acid, which are essential for healthy tissue function and hydration.
