L-Selenomethionine Chemical Properties,Uses,Production
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.
Synthesis of L-Selenomethionine from L-Homoserine lactone hydrochloride and Methaneselenol, sodium salt (9CI)
