一般描述
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。
应用
- 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）。

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
