Metabolite Identification
Common NameSe-Methylselenocysteine
DescriptionSe-se-methylselenocysteine, also known as se-methylselenocysteine or se-methylselenocysteine, belongs to the class of organic compounds known as l-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. Se-se-methylselenocysteine is possibly soluble (in water) and a very strong basic compound (based on its pKa). Se-se-methylselenocysteine exists in all living species, ranging from bacteria to humans. Se-se-methylselenocysteine can be converted into Gamma-glutamyl-se-se-methylselenocysteine through the action of the enzyme Gamma-glutamyltranspeptidase 1. In cattle, se-se-methylselenocysteine is involved in the metabolic pathway called the selenoamino acid metabolism pathway.
