L-Selenomethionine (CAS 3211-76-5) is a sulfur-containing amino acid analog that has garnered significant attention across various scientific disciplines. Its unique properties, stemming from the incorporation of selenium, make it a valuable compound for researchers and formulators alike. As a leading provider of high-quality amino acids, we offer L-Selenomethionine that meets the rigorous demands of scientific research and industrial applications. For those looking to buy L-Selenomethionine, understanding its diverse applications is key.

The Cornerstone of Protein Structure Determination

One of the most critical applications of L-Selenomethionine lies in its use for protein structural analysis. In techniques like X-ray crystallography, determining the phase of diffracted X-rays is essential for reconstructing a 3D protein model. Methionine is a common amino acid, and its replacement by L-Selenomethionine introduces selenium atoms, which are heavy atoms with distinct X-ray scattering properties. This 'heavy atom derivative' approach, often referred to as the 'seleno-methionine derivative method', greatly simplifies phase determination. Researchers rely on consistent supply from a trustworthy L-Selenomethionine supplier China to produce these critical derivatives for their structural biology studies.

Antioxidant and Health Benefits

Beyond its utility in structural biology, L-Selenomethionine is recognized for its significant role in human health. As the primary dietary form of selenium, it is readily incorporated into selenoproteins, which are crucial for antioxidant defense. These proteins, such as glutathione peroxidase, protect cells from oxidative damage by neutralizing harmful reactive oxygen species. This makes L-Selenomethionine a popular ingredient in dietary supplements aimed at boosting antioxidant status, supporting immune function, and potentially offering protective benefits against certain diseases. This growing demand translates into an active search for competitive L-Selenomethionine price inquiry from manufacturers.

Pharmaceutical Research and Development

The potential therapeutic and chemoprotective effects of L-Selenomethionine are also subjects of active pharmaceutical research. Its ability to induce apoptosis in cancer cell lines and mitigate oxidative stress makes it a compound of interest for developing new treatment strategies. For pharmaceutical companies, securing a reliable supply of high-purity L-Selenomethionine from a qualified L-Selenomethionine supplier China is a critical aspect of their R&D pipeline.

Sourcing Strategies for L-Selenomethionine

Procuring L-Selenomethionine involves careful selection of suppliers. Factors to consider include purity levels (often specified by HPLC or titration), adherence to pharmacopoeial standards (USP, BP, EP), packaging options, and reliable delivery timelines. Working with manufacturers that provide detailed technical documentation and have robust quality management systems ensures that your procurement needs are met efficiently and effectively.

In conclusion, L-Selenomethionine is a compound with profound implications, bridging the gap between fundamental scientific research and practical health applications. Its continued importance in protein structure determination and its role in cellular antioxidant defense highlight the need for dependable sourcing from experienced chemical manufacturers.
