Z-L-Methionine is widely used in biochemical research as a protective agent for amino groups during peptide synthesis. Its application is crucial in the production of peptides and proteins, where it helps maintain the integrity of the amino acid sequence. Additionally, it serves as a precursor in the synthesis of various pharmaceuticals, particularly those targeting liver disorders and detoxification processes. In agricultural practices, it is incorporated into animal feed to enhance growth and improve overall health by providing essential sulfur-containing amino acids. Its role in these diverse fields underscores its importance in both scientific and industrial applications.
