DL-Cysteine, identified by CAS number 3374-22-9, is an alpha-amino acid with a thiol side chain. Its chemical structure (C3H7NO2S) confers unique properties that make it highly valuable across multiple industrial sectors, including pharmaceuticals, food science, and biotechnology. Understanding these properties is key for R&D professionals and procurement managers seeking to leverage its capabilities. As a leading DL-Cysteine manufacturer, we provide insights into its fundamental chemistry and industrial applications.
The defining feature of DL-Cysteine is its thiol (-SH) group, which is highly reactive and prone to oxidation. This reactivity is the basis for its potent antioxidant activity, as it can readily donate a hydrogen atom to neutralize free radicals. This property is critically important in pharmaceutical development, where DL-Cysteine is used to create detoxifying agents and antioxidants that protect against cellular damage. For companies looking to buy DL-Cysteine for these applications, its chemical stability and reactivity profile are key considerations. We ensure our manufactured DL-Cysteine meets rigorous purity standards suitable for these sensitive applications.
In the food industry, the chemical behavior of DL-Cysteine influences flavor development through Maillard reactions and provides preservative qualities by scavenging oxygen. Its reducing properties help maintain product color and prevent rancidity. As a DL-Cysteine supplier, we highlight these functional attributes that contribute to improved product quality and shelf-life. Understanding the molecular weight (121.16 g/mol) and solubility characteristics of DL-Cysteine is also important for effective formulation design.
For biotechnology and biochemical research, DL-Cysteine's role in protein synthesis, folding, and as a cofactor for enzymes underscores its fundamental importance. Its ability to form disulfide bonds is essential for the structural integrity of many proteins. Researchers often seek out reliable DL-Cysteine manufacturers to ensure consistent performance in cell culture media and biochemical assays. We are dedicated to being a premier DL-Cysteine supplier, offering high-quality material that supports scientific discovery and innovation. If you are looking to procure DL-Cysteine for industrial or research purposes, we invite you to inquire about our product specifications and pricing.
