  • Lysine isotopologues, compositions comprising the same and methods of synthesis
    Patent number: 9840457
    Abstract: This invention relates to lysine isotopologues of Formulas I and 1-A, as described herein, and processes for synthesizing the same and derivatives and intermediates involved therein. In one aspect, described herein is a chemical compound comprising an isotopically labeled analog, i.e., an isotopologue of a standard or naturally occurring lysine. The lysine isotopologue is synthetically formed to have stable isotopes of elements incorporated at selected positions. As such, the lysine isotopologue has a molecular mass different from the mass of a standard or naturally occurring lysine.
