Introducing selenium: The synthesis and full characterization of human hepatic Se metabolite A has been accomplished by using a robust, efficient, and Cys‐specific selenenylation protocol (see scheme; NaPi=sodium phosphate). The selenenylsulfide linkage is sufficiently stable to allow quantification of Se‐containing glycoconjugates in biological fluids by using atomic detection methods.
硒介绍:人肝硒代谢物 A 的合成和完整表征是通过使用稳健、高效和半胱氨酸特异性硒化方案完成的(参见方案;NaPi=磷酸钠)。硒基硫键足够稳定,可以使用原子检测方法对生物体液中的含硒糖缀合物进行定量。
