Chemical Information
FooDB Name3-(Methylseleno)alanine
DescriptionSe-Methylselenocysteine (SeMSC) is a naturally occurring seleno-amino acid that is synthesized by plants such as garlic, astragalus, onions and broccoli. Unlike selenomethionine, which is incorporated into proteins in place of methionine, SeMSC is not incorporated into any proteins, thereby being fully available for the synthesis of selenium-containing enzymes such as glutathione peroxidase. 3-(Methylseleno)alanine is found in many foods, some of which are common cabbage, white cabbage, lima bean, and cauliflower.
