Sodium 2-aminoethanesulfonate, also known as sodium taurate, is the sodium salt of taurine (2-aminoethanesulfonic acid), a naturally occurring sulfur-containing beta-amino acid. It is widely used in biochemical and physiological research due to taurine's roles in osmoregulation, membrane stabilization, calcium modulation, and antioxidant protection. Commonly employed in cell culture media to support neuronal and cardiac cell growth, in studies of neuroprotection, cardiovascular function, and bile acid conjugation. Also utilized in pharmaceutical formulations as a stabilizer and active ingredient in supplements for eye health, energy drinks, and metabolic support. Its high solubility in water and biocompatibility make it suitable for various biomedical applications, though it is not primarily used as a pH buffer.
