一般說明
β-来自玛瑙螺的H-2型葡糖醛酸糖苷酶是从罗马蜗牛的消化液中提取的酶的粗溶液。β-来自软体动物的葡糖醛酸糖苷酶也有硫酸酯酶活性。两种活性都可用于代谢物的水解，用于毒理学和生物标志物分析。如需更广泛地了解我们的β-葡糖醛酸糖苷酶产品线及其用途，请参阅我们有关药物代谢物分析的页面
應用
- 通过消化与葡萄糖醛酸苷结合的化合物而制备的LC / MS样品，用于生物标志物和毒理学研究。
- 去除葡萄糖醛酸苷结合物，例如用于制备黄芩素。
生化／生理作用
内源性β-葡糖醛酸糖苷酶是一种溶酶体酶，参与了葡萄糖醛酸苷修饰的分解代谢产物的消化。
在微生物群中发现的微生物β-葡糖醛酸糖苷酶可以通过水解异种生物质和内生代谢物的葡萄糖醛酸苷结合物而引起代谢物的重吸收。
