  "term": "Glycosaminoglycan",
  "field": "Chemistry",
  "definition": "Long, unbranched polysaccharide chains composed of repeating disaccharide units, where one sugar is an amino sugar (N-acetylglucosamine or N-acetylgalactosamine) and the other is usually a uronic acid. These highly negatively charged molecules are a major component of the extracellular matrix, providing structural support and lubrication. Hyaluronic acid, chondroitin sulfate, and heparin are examples of glycosaminoglycans.",
