Se-methylselenocysteine modulates antioxidant response of rat spleen to ionizing radiation

Determination of selenium species and analysis of methyl-seleno-l-cysteine in Se-enriched mung bean sprouts by HPLC-MS

“…[23][24][25] Se-MeSeCys is a small molecule organic selenium compound which has higher biological activity and less systemic toxicity than either inorganic Se or other organic Se compounds such as Se-Met. 26,27 Se-MeSeCys mainly exists as free Se-MeSeCys, which is a nonprotein amino acid, which means that it does not participate in protein biosynthesis. Also, a portion of the organic Se exists as non-protein compounds, and organic Se may have been lost in the process of extraction and the enzymatic hydrolysis of protein.…”
