Hyaluronic acid,molecular model. Hyaluronic acid (or hyaluronon) is a glycosaminoglycan,a type of biological polymer made up of repeating units of a disaccharide (two sugar molecules) formed of D- glucuronic acid and D-N-acetylglucosamine. It is widely distributed in connective tissues,joints and skin. It acts as a lubricant in joint spaces,and is a major component of cartilage and skin. Because of this it has found uses in medicines and cosmetics,as Healon for use in eye surgery and Restylane for wrinkle removal. Only a small part of the molecule is seen here; the polymer may be many thousands of units long. Atoms are colour- coded: carbon (yellow),oxygen (red),nitrogen (blue),hydrogen (white) and sodium ions (grey) | |
