Hyaluronic Acid (Glycoaminoglycan) can be found throughout the body as part of the supporting structure in extracellular spaces. Hyaluronic Acid is a polysaccharide chaing of repeating disaccharide units. It is found most abundantly in cartilage, synovial fluid, skin, and the aqueous humor in the eye. The disaccharide chain consists of sodium acetyl glucosamine and sodium glucuronate. Hyaluronic Acid is obtained from rooster combs and from bacterial fermentation. The viscosity of hyaluronic acid increases as the concentration, molecular weight, and polysaccharide chain length increase.
Hyaluronic Acid is useful for physical lubricating and cushioning. In addition, hyaluronic acid may contribute to antioxidant activity and modulate the immune system. It can be used topically as well for wounds, burns, ulcers, and moisturizing the skin. Orally, hyaluronic acid is most often used for joint disorders and preventing the effects of aging. Hyaluronic Acid can also be injected.
