Cystine Disodium Salt Supplier

The disulfide bond (-S-S-) is the most reactive functional group in Cystine Disodium Salt, and its redox conversion with thiol groups (-SH) is a core reaction in biological systems.
  • Reduction reaction: Under mild reducing conditions, the disulfide bond is cleaved to generate two molecules of sodium cysteinate. Common reducing agents include dithiothreitol (DTT), β-mercaptoethanol, and sodium sulfite. For example, in the presence of DTT (molar ratio 1:1), Cystine Disodium Salt is completely reduced to sodium cysteinate in an aqueous solution at 37 °C within 30 minutes. This reaction is reversible and is widely used in protein chemistry to break disulfide bonds in denatured proteins.
  • Oxidation reaction: Conversely, sodium cysteinate can be oxidized back to Cystine Disodium Salt by exposure to air or mild oxidants (e.g., hydrogen peroxide, iodine solution). In the presence of trace metal ions (e.g., Cu²⁺, Fe³⁺), this oxidation reaction is significantly accelerated, which is why Cystine Disodium Salt formulations often add metal chelators (e.g., EDTA) to improve stability.
  • Disulfide exchange reaction: Cystine Disodium Salt can undergo disulfide exchange with other thiol-containing compounds (e.g., glutathione, cysteine). This reaction is critical for maintaining the redox balance of biological systems and regulating the structure and function of proteins containing disulfide bonds.
