一般描述

透明质酸（HA）是中枢神经系统细胞外基质的重要组分，是在所有脊椎动物结缔组织中都能发现的多功能大分子。这种超分子糖胺聚糖是一种聚阴离子天然聚合物，以线性多糖的形式存在。它由葡萄糖醛酸和N-乙酰氨基葡萄糖通过β-1,4键重复组成。透明质酸在眼睛、关节和心脏瓣膜中大量存在。

应用

马链球菌透明质酸钠盐已用于：
  • 与甲基丙烯酸酐合成交联甲基丙烯酸 HA 水凝胶（Coll-MeHA）
  • 在磷酸盐缓冲盐水（PBS）中取代 PBS 浴槽来改变润滑剂成分
  • 制备润滑剂，以研究对人体骨关节炎（OA）软骨边界润滑的影响

生化/生理作用

透明质酸（HA）是滑膜液和关节软骨的重要组分，起边界润滑剂的作用。它具有多种物理化学性质，包括生物可降解性、生物相容性、无毒性和非免疫原性。透明质酸被认为是生物医学用途的重要工具，如药物输送、组织工程、整形外科、眼科手术和骨关节炎手术。它参与身体缓冲和润滑。这种强大的抗氧化剂可以将水与组织结合。
