一般說明
亚硒酸是一种二元酸。它是硒的含氧酸，可以通过将二氧化硒气体加入水中而形成。亚硒酸类似于亚硫酸。 作为结晶固体，分子排列成金字塔形，在溶液中表现为二质子酸。
應用
- 用于设计析氧反应的高反应活性电催化剂的硒酸蚀刻辅助空位工程（vacancy engineering）：考察了硒酸在电催化剂的空位工程中的用途（Zhang et al., 2021）。
- 水性硫酸溶液中硒酸引起的硫堇还原的铕（III）催化剂研究了水性硫酸溶液中硒（IV）还原的动力学和机制 （Fawzy, 2016）。

1,2-Oxaselenolane Se-oxide is a novel cyclic seleninate ester that functions as a remarkably efficient glutathione peroxidase mimetic by catalyzing the reduction of tert-butyl hydroperoxide to tert-butyl alcohol in the presence of benzyl thiol. The seleninate ester can be conveniently generated

The genotoxic activity of three selenium compounds (sodium selenite, sodium selenate, and selenious acid) and the antigenotoxic effects of sodium selenite in combination with the chromium compound potassium dichromate were studied using the wing spot test of Drosophila melanogaster. This

Selenium-dependent glutathione peroxidase (GPx) plays a protective role in oxidative stress-induced apoptosis. In this study, we demonstrated that MDBK cells, a bovine renal epithelial cell line, exhibited internucleosomal DNA fragmentation characteristic of apoptotic cell death under selenium-deficient conditions with lower

All nutritional selenium sources are transformed into the assumed common intermediate selenide for the syntheses of selenoproteins for utilization and/or of selenosugar for excretion. Methylselenol [monomethylselenide, MMSe] is the assumed intermediate leading to other methylated metabolites, dimethylselenide (DMSe) and trimethylselenonium
