Abstract
The metabolism of selenomethionine in Astragalus crotalariae (a selenium-accumulating species) differs from that in Astragalus lentiginosus (a non-accumulator). After the administration of [75Se]selenomethionine and [Me-14C]selenomethionine to excised leaves of A. crotalariae, Se-methylselenomethionine,Buy Microsoft Office 2010, Se-methylselenocysteine,Windows 7 Professional X64, and selenohomocystine were identified as the soluble components. A. lentiginosus formed mainly Se-methylselenomethionine,Office 2007 Enterprise Product Key, and a seleno peptide all of whose constituent amino acids have not been identified.
When [35S]methionine was administered to A. crotalariae a small amount was converted to S-methylmethionine but most was recovered as methionine. Homocrystine and S-methylcysteine were not formed in detectable amounts.
