Description:
Hyaluronic acid(HA) is a straight chain macromolecular mucopolysaccharide composed Of repeat disaccharide units of glucuronic acid and N-acetylglucosamine. It widely consists in the extracellular space of human and animal tissue, vitreum, umbilical cord, skin joints synovia and cockscomb, etc. The commercial HA is commonly a sodium salt, called sodium hyaluronate, habitually called hyaluronic acid. HA is a new biological at home and abroad. Its molecular weight is from several ten thousand to several million. It's aqueous solution has outstanding moisture keeping ability, high viscoelasticity and lubricity. It is widely used in cosmetics, pharmacy and health and beauty food.
[Application]
Hylauronic acid (HA) is part of the glycosaminogly family; it's a complex carbohydrate that's vital to our well-being. Hyaluronic acid fastens onto our collagen and elastin and creates cartilage. It's found in every tissue of our body, and is responsible for carrying out a number of vital functions.
