L-Selenomethionine Chemical Properties,Usage,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.
