L-LEUCINE (D10; 15N) is an isotopically labeled, free L-leucine amino acid in which the leucine side-chain contains deuterium (D10) and the amino group is labeled with nitrogen-15 (15N), maintaining the characteristic branched aliphatic isobutyl side chain of leucine. The molecule bears an α-amino group and an α-carboxyl group, with the labeled nitrogen on the amino functionality and deuterium distributed on the carbon framework, enabling retention of leucine's general chemical behavior while shifting its mass and isotopic signatures. L-LEUCINE (D10; 15N) is used in isotopic tracing, mass spectrometry-based analytical method development, and quantitative studies of amino acid incorporation or turnover where isotopic discrimination between labeled and unlabeled leucine is required.
