Conditionally essential amino acids for human body ---- Taurine Powder

Taurine is a sulfur-containing amino acid with simple structure in animals. Its chemical name is 2-aminoethanesulfonic acid. Its molecular formula is C2H7NO3S and its molecular weight is 125.15. It is odorless and slightly sour. Its dilute solution is neutral and stable to heat. It binds with cholic acid in human and animal bile and exists in the form of binding; In brain, ovary, heart, liver, milk, pineal gland, pituitary, retina, adrenal gland and other tissues, it exists in free form, with a total amount of 12-18g, but does not participate in protein synthesis. Taurine is a conditionally essential amino acid for human body and plays an important role in the development of fetal and infant nervous system. Taurine can be widely used in medicine, Food Additives, fluorescent brighteners, organic synthesis and other fields. It can also be used as biochemical reagent, wetting agent, pH buffer and so on.

Taurine is an amino acid transformed from sulfur-containing amino acids, also known as taurine, taurine, taurine choline and taurine. Taurine is widely distributed in various tissues and organs in the body, and mainly exists in interstitial fluid and intracellular fluid in free state. It was first found in bull bile and got its name, but it has long been considered as a non functional metabolite of sulfur-containing amino acids. Taurine is a sulfur-containing amino acid in animals, but it is not a component of protein. Taurine is widely distributed in human and animal brain, heart, liver, kidney, ovary, uterus, skeletal muscle, blood, saliva and milk in the form of free amino acids, with the highest concentration in pineal gland, retina, pituitary gland, adrenal gland and other tissues. In mammalian heart, free taurine accounts for 50% of the total free amino acids.

Application

Pharmaceutical industry

Taurine has anti-inflammatory, antipyretic, analgesic, sedative, hypotensive, hypoglycemic, antiarrhythmic, antibacterial, antiplatelet aggregation, enhancing immune function, cholagogic, liver strengthening, detoxification, regulating vascular tension and other functions. It can be used for the treatment of acute and chronic hepatitis, fatty liver, cholecystitis, bronchitis, tonsillitis, acute conjunctivitis Herpes and viral conjunctivitis; It is also used to treat colds, fever, epilepsy, infantile spasms, heart failure, arrhythmia, hypertension, uterine bleeding, arteriosclerosis, acne and so on. As a drug, taurine has been widely used in China and Japan.

food additives

Taurine is an essential amino acid for human and animals. The lack of taurine in children may lead to dysplasia, visual impairment, increased susceptibility to epilepsy, and even cardiomyopathy; The lack of taurine in adults also endangers their health. As an excellent food additive, taurine has been widely used in developed countries such as Europe, America and Japan. In order to ensure the healthy growth of infants and young children, the United States, Japan and other countries have already clearly stipulated that the content of taurine in infant dairy products shall not be less than 0.16mg/100ml. Taurine was added to certain nutritional supplements sold in Japan as early as the 1970s. They also add it to beverages, compound monosodium glutamate, soy products and dairy products. In Japan, children's food is not allowed to be sold without taurine. 99% of taurine in the United States, Japan and other countries is used as food additive. China started late in this field. In 1990, taurine was allowed to be added to dairy products, beverages and composite condiments as a nutritional food additive, with the allowable addition amount of 30 ~ 40mg / kg. In recent years, the "Red Bull" beverage, "Wahaha" children's nutrient solution, "congcongcong mother solution" and "Qiangli God", "golden Oyster", "Longdan" and other nutritional and health products emerging in the market all contain an appropriate amount of taurine. Research shows that adding an appropriate amount of taurine to milk and milk powder can have a nutritional value close to that of breast milk. Taurine can also be used as a high-quality additive for food and beverages of pilots, astronauts and athletes to enhance physique and relieve fatigue. In addition, taurine is added to animal feed as a Feed Additive, which can prevent fish diseases and make the eyes of cats, dogs and other pets brighter. It is expected that taurine will be mainly used as food nutritional additives in the future. The market for food additives will be very broad and will produce great economic and social benefits. 

Organic synthesis intermediate

It is used in the synthesis of fluorescent brightener. For example, the introduction of aminoethanesulfonic acid group into stilbene bis triazine fluorescent brighteners can improve the water solubility of brighteners and enhance the washing and whitening effect. This kind of brightener is mainly used for the whitening of papermaking, cellulose fiber and polyamide fiber. In addition, taurine can be reacted with polyacrylamide to make functional polymer flocculant n-taurine polyacrylamide, which can be used in the gypsum separation process of wet process phosphoric acid. Because it can control the crystal form of gypsum and reduce the viscosity of phosphoric acid in the process of gypsum formation, it can improve the filtration speed and increase the filtration efficiency. Taurine can also be used in the preparation of reactive dyes and the synthesis of other organic compounds.
