主要成分 Main Component |
透明质酸钠为透明质酸(HA)的钠盐,是由 D-葡萄糖醛酸与 N-乙酰-D-葡萄糖胺交替 β-糖苷键连接而成的线性阴离子多糖(糖胺聚糖);广泛存在于人体皮肤、关节滑液与眼玻璃体,由发酵法(兽疫链球菌等)或动物组织提取制得。 Sodium hyaluronate is the sodium salt of hyaluronic acid (HA), a linear anionic polysaccharide (glycosaminoglycan) of alternating D-glucuronic acid and N-acetyl-D-glucosamine via β-glycosidic bonds; widely present in human skin, synovial fluid and vitreous. Produced by fermentation (Streptococcus etc.) or extraction. |
