应用
聚半乳糖醛酸可螯合金属离子。 它还可在Ca2+存在下产生凝胶，从而用于药物释放或在生物分子生产中固定细胞或酶。
生化/生理作用
在陆生植物中，聚半乳糖醛酸是细胞壁多糖（果胶）的主要成分。与多聚半乳糖醛酸酶抑制肽（PGIP）结合可保护果胶免于被真菌多聚半乳糖醛酸酶降解。

This study has investigated the potential of immersion coating calcium containing pellet cores first with pectin, and then with two different cross-linkers, calcium or chitosan. The interaction between pectin and calcium, and between pectin and chitosan, are believed to slow
实验方案
To measure pectinase activity, a titrimetric stop reaction assay is used. One unit of pectinase will liberate 1 μmol of galacturonic acid from poly-galacturonic acid per hour at pH 4.0 at 25 °C.
在测定果胶酶活性时，使用了一种滴定终止反应法进行测定。在25 °C、pH 4.0条件下，一个单位的果胶酶每小时可从多聚半乳糖醛酸释放1 μmol 的半乳糖醛酸。
