Hyaluronic acid
Hyaluronic acid (hyaluronic acid, sodium hyaluronate, abbreviated as HA), also known as hyaluronic acid, hyaluronic acid, is a polymer mucopolysaccharide composed of N-acetylglucosamine and D-glucuronic acid disaccharide units repeatedly linked. Commercially available hyaluronic acid is generally in the form of its sodium salt, called sodium hyaluronate.
