Sodium hyaluronate is a physiologically active substance widely present in the human body.
It is a high-molecular-weight linear mucopolysaccharide composed of disaccharide units composed of glucuronic acid and acetaminohexose. Its molecular weight is 1 million.
It forms a thick viscoelastic solution in water with physiological pH and ionic strength. Its molecular shape is variable, so it can also be passed through with a thinner injection needle.
