Overview
N-Acetyl-L-methionine丨CAS 65-82-7 is a modified amino acid commonly used in nutrition, pharmaceuticals, and biochemical research due to its enhanced stability and unique functional properties compared to free methionine.
Applications
1. Nutritional Supplements
Methionine Source:
Used as a dietary supplement providing methionine, an essential amino acid important for protein synthesis, methylation reactions, and antioxidant functions.
Enhanced Stability:
The N-acetylation improves stability against enzymatic degradation, allowing better absorption and bioavailability in nutritional formulations.
2. Pharmaceutical Industry
Intermediate in Drug Synthesis:
Utilized as a building block in the synthesis of pharmaceuticals, especially peptides or drugs requiring methionine residues with protected amino groups.
Protecting Group in Peptide Chemistry:
The acetyl group protects the amino group during peptide bond formation, allowing selective reactions and minimizing side reactions.
3. Biochemical and Research Applications
Study of Methionine Metabolism:
Used in biochemical assays and research focused on methionine metabolism, methylation pathways, and sulfur amino acid biology.
Enzyme Substrate or Inhibitor:
Sometimes used in enzyme kinetics studies related to methionine metabolism or modification.
Benefits
1. Improved Stability
N-Acetyl-L-methionine丨CAS 65-82-7 protects the amino group from unwanted reactions, increasing shelf-life and resistance to enzymatic breakdown compared to free L-methionine.
2. Enhanced Bioavailability
The modification can improve the pharmacokinetic profile of methionine when administered orally or in formulations.
3. Versatile Synthetic Intermediate
Allows selective chemical reactions in peptide synthesis and organic chemistry due to the acetyl protecting group.
Conclusion
N-Acetyl-L-methionine丨CAS 65-82-7 is an important N-protected amino acid derivative widely used in nutrition, pharmaceutical synthesis, and biochemical research. Its enhanced stability and functional versatility make it valuable for improving methionine delivery in supplements and facilitating selective reactions in synthetic chemistry.
