Chondroitin Sulfate Glycosaminoglyans (GAGs)
- Joint and bone shock absorber
- Support extracellular matrices
- Amass water in stress areas (highly hydrophilic)
- Pain relief
- Vital components of cartilage
Disaccharide chains, powerful anti-aging compounds.
A sulfated glycosaminoglycan (GAG), chondroitin is a vital component of extracellular matrices (ECM). ECM is in all organs and tissues, a three dimensional grouping of proteins, water, and polysaccharides. An intricate molecular network that supports surrounding cells. Chondroitin sulfate can carry biological information in its alternating disaccharide chain, i.e., galactosamine and glucuronic acid alternating [2, 3].
Highly polar, GAGs attract water, also a main component of ECM. ECM being vital to tissues, organs, joints, bones, ligaments, and cartilage. ECM and its strong hydrophilic properties allow matrices to amass great volumes of water, allowing
the areas of pressure and stress that the matrices usually reside in to sustain hefty pressures and physical stressors similar to the functions of shock absorbers .
Chondroitin sulfate has become a popular dietary ingredient due to its pain relieving effects in joints, bones, and areas commonly affected by osteoarthritis. Double blind, placebo controlled, clinical trials show significant pain relief in chondroitin supplementation groups relative to placebo groups [4, 5, 6]. Show more...
