透明质酸是构成人体细胞间质、眼玻璃体、关节滑液等结缔组织的主要成分，在体内发挥保水、维持细胞外空间、调节渗透压、润滑、促进细胞修复的重要生理功能。透明质酸分子中含有大量的羧基和羟基，在水溶液中形成分子内和分子间的氢键，这使其具有强大的保水作用，可结合自身400倍以上的水；在较高浓度时，由其分子间作用形成的复杂的三级网状结构，其水溶液又具有显著的粘弹性。透明质酸作为细胞间基质的主要成分，直接参与细胞内外电解质交流的调控，发挥物理和分子信息的过滤器作用。大分子透明质酸对细胞移动、增殖、分化及吞噬功能有抑制作用，小分子透明质酸则有促进作用。透明质酸具有独特理化性质和生理功能，在医学方面已得到广泛应用
Hyaluronic acid is the main component of connective tissues such as intercellular matrix, vitreous humor, and synovial fluid in the human body. It plays an important physiological role in water retention, maintaining extracellular space, regulating osmotic pressure, lubrication, and promoting cell repair in the body. Hyaluronic acid molecules contain a large number of carboxyl and hydroxyl groups, which form hydrogen bonds within and between molecules in aqueous solutions, giving them strong water retention properties and the ability to bind to over 400 times their own amount of water; At higher concentrations, the complex tertiary network structure formed by intermolecular interactions exhibits significant viscoelasticity in its aqueous solution. Hyaluronic acid, as the main component of the intercellular matrix, directly participates in the regulation of electrolyte exchange inside and outside the cell, playing a filtering role in physical and molecular information. Large molecule hyaluronic acid has inhibitory effects on cell movement, proliferation, differentiation, and phagocytic function, while small molecule hyaluronic acid has promoting effects. Hyaluronic acid has unique physicochemical properties and physiological functions, and has been widely used in medicine
