Taurine Powder CAS#107-35-7
Taurine is an organic compound that is widely distributed in animal tissues and belongs to the class of sulfur-containing amino acids. Unlike proteinogenic amino acids, taurine is not involved in protein synthesis but plays a significant role in various biological processes. It is naturally abundant in tissues such as the brain, heart, gallbladder, and kidneys.
Taurine is an essential nutrient for preterm infants and newborns, supporting normal growth and development. It performs multiple physiological functions, including acting as a neurotransmitter in the brain, promoting bile acid binding, providing antioxidant effects, maintaining osmotic balance, stabilizing cell membranes, regulating calcium signaling, supporting cardiovascular health, and contributing to the development and function of skeletal muscle, the retina, and the central nervous system.

Taurine is a naturally occurring organic acid widely present in animal tissues and serves as an important component of bile. It performs various biological functions, including bile acid conjugation, antioxidant activity, osmotic regulation, cell membrane stabilization, and modulation of calcium signaling pathways.
As an amino acid nutritional supplement, taurine is commonly used to support health and treat taurine-deficiency-related conditions, such as dilated cardiomyopathy, a form of heart disease associated with impaired cardiac function.
