Methionine Sulfoximine

L-methionine sulfoximine is a methionine sulfoximine with S-stereochemistry at the amino group. It functions as a geroprotector and inhibitor of EC 6.3.1.2 (glutamate--ammonia ligase). It is a L-methionine derivative, a non-proteinogenic L-alpha-amino acid, and a tautomer of a L-methionine sulfoximine zwitterion.
