Hyaluronic Acid (HA)
Hyaluronic Acid (hyaluronan)
also known as hyaluronan or hyaluronate, is a hydrophilic (waterloving) carbohydrate found naturally throughout the human body. First isolated by Karl Meyer in 1934, HA is comprised of the molecules N-acetyl glucosamine and glucuronic acid. Its linear, rope-like structure allows it to bind up to 1,000 times its weight in water. As HA seeks out and binds to water, it becomes a viscous, Jell-O-like substance that serves as the body’s natural lubricant and provider of cushioning and elasticity.
