Also called sodium hyaluronate sodium hyaluronate.
In 1934, Meyer and other bovine vitreous (hyaloid body) isolated a uronic acid-containing (uronic acid) and polysaccharide of hexosamine, named "hyaluronic acid". The term "hyaloid" (transparent, glass-like) and "uronic acid" combination, and the bio-chemical terms translated as "hyaluronic acid", the pharmacopoeia of drugs and the national drug standards is known as "acid." In physiological neutral environments, hyaluronic acid is a polyanionic. In 1985, Balazs proposals "Hyaluronan" term as the General name of this polysaccharide, regardless of the degree of dissociation is in degrees. "Hyaluronan" has been widely covered any State of hyaluronic acid and its salts (hyaluronate), usually translated as "hyaluronic acid", abbreviated as HA. At present, drugs size of HA products are usually referred to as sodium hyaluronate injection, and the weapon size HA products called medical sodium hyaluronate gel.
Streptococcus zooepidemics (s.zooepidemicus) mutant (mutant) production from fermentation. This mutant no hemolytic activity, producing large amount of sodium hyaluronate, product molecular weight can be up to 2.5 million.
