L-Selenomethionine Usage And Synthesis

Chemical Properties	Solid
Uses	A compound shown to increase expression of glutathione peroxidase
Uses	Seleno-L-methionine has been used: in toxicity studies in Japanese Medaka embryos to study its effects on selenium status indicators in pregnant long-tailed macaques (Macaca Fascicularis) to label proteins for single wavelength anomalous dispersion (SAD) phasing
Definition	ChEBI: The L-enantiomer of selenomethionine.
General Description	Seleno-L-Methionine (SeMet), an organic form of selenium is found in Cupriavidus metallidurans.
Biochem/physiol Actions	Seleno-L-Methionine (SeMet) is capable of repressing atopic dermatitis (AD)-like skin lesions. It can also prevent the expression of total immunoglobulin E (IgE) and interleukin 4 (IL-4). It can cause ecotoxicity as it is absorbed by fish through diet.
