Overview
Sodium taurodeoxycholate is a conjugated bile salt formed by the combination of taurine with deoxycholic acid. It is a naturally occurring component in mammalian bile but is also synthesized for industrial and research purposes. As an amphipathic molecule, it plays critical roles in lipid digestion and absorption in biological systems. Its detergent properties make it invaluable in laboratory applications, particularly in membrane protein studies.
Physical and Chemical Properties
This crystalline compound exhibits high solubility in aqueous solutions, forming micelles above its critical micelle concentration (CMC). Its molecular structure contains both hydrophilic (sulfonate and hydroxyl groups) and hydrophobic (steroid backbone) regions. The compound is stable under recommended storage conditions but may degrade upon prolonged exposure to light or elevated temperatures. Its pH in solution is typically neutral to slightly alkaline.
Main Applications
In biochemical research, sodium taurodeoxycholate is primarily used for cell membrane disruption and protein solubilization. It's particularly effective for extracting membrane-bound proteins while maintaining their native conformation. The pharmaceutical industry utilizes it as an excipient in drug formulations to enhance solubility of poorly water-soluble compounds. It also finds application in diagnostic kits and as a reference standard in analytical chemistry.
Safety and Storage
While not classified as highly hazardous, proper handling precautions should be observed. The powder may cause irritation to respiratory system, skin and eyes upon direct contact. Long-term storage should be in tightly sealed containers under refrigeration. Solutions should be prepared fresh when possible, as microbial growth may occur in aqueous preparations over time. Always consult the SDS for specific handling instructions.
B2B Procurement Guide
When sourcing sodium taurodeoxycholate, prioritize suppliers with demonstrated expertise in bile acid derivatives. Key procurement considerations include analytical certificates (HPLC purity, heavy metal content), batch-to-batch consistency, and appropriate packaging options. For large-scale pharmaceutical use, ensure the supplier can provide GMP-grade material with full documentation. Smaller research quantities are typically available from specialty chemical distributors with shorter lead times but may command higher unit prices.
