1. Hyaluronic Acid has excellent affinity for water and reorganizes water within the organization to better bear load or lubrication.
2. Folding occurs to form a three-dimensional network, producing physiological effects. This includes generating fluid resistance, maintaining internal water balance and environmental stability, affecting the solubility, spatial configuration, chemical balance, and system osmotic pressure of biological macromolecules, preventing the spread of pathogens, and guiding the deposition of collagen fiber secretory substances.
3. Connect with proteins that cannot be separated to form polymers, maintain the shape and volume of the tissue Chemicalbook, and ensure the reversible compressive strength of the tissue.
4. It has certain effects on macrophages, mucocytes, lymphocytes, and natural killer cells.
5. Hyaluronic acid (HA) is an important component of intercellular matrix, mainly degraded in the liver. During the activity of liver fibrosis, the synthesis of HA increases, coupled with decreased function during cirrhosis, resulting in an abnormal increase in blood HA levels. At present, HA is a highly sensitive and specific indicator for diagnosing the degree of liver fibrosis and cirrhosis.
