• 介绍：

   Polygalacturonic acid (Galacturonic acid polymer) 是透明胶状酸，是细胞壁的主要成分。Polygalacturonic acid 可用于制备银纳米颗粒 (AgNPs)，作为抗氧化剂和抗炎剂，保护细胞免受 ROS 升高的破坏作用，并加速伤口愈合。Polygalacturonic acid 纳米颗粒也表现出抗菌活性。

• 溶解性： 0.1mol/L柠檬酸-柠檬酸钠缓冲液  酸性缓冲液煮沸搅拌溶解

• 敏感性： 易吸潮

• 储存条件： RT

• 用途： 对于陆生植物，聚半乳糖醛酸是细胞壁多糖（果胶）的主要组成部分。束缚果胶酶酶抑制肽（PGIP），保护果胶，防止真菌果胶酶降解果胶。
