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. |
