Molecular formula :
CAS :
nature : names Sulfhydryl alanine. A colorless crystal. A sulfhydryl-containing amino acid. White hair extract derived and used its hydrochloride. Microcredit is foul. Dissolved in water, ethanol, acetic acid and ammonia, is not soluble in ether, acetone, ethyl acetate, benzene, carbon tetrachloride and carbon disulfide. In neutral or slightly alkaline solution can be oxidized to air cystine. More medicine for hepatitis, antimony poisoning agent, radioactive poisoning, prevention of liver necrosis, etc., are also available biochemistry and nutrition research. May protein (ICPD) with hydrochloric acid hydrolysis, then copper oxide, in which decomposition of hydrogen sulfide. Cystine degradation may also be derived. Electrolysis. L-cystine hydrochloride in cathodic current role, the elements of disulfide fracture, and hydrogenation generation L-cysteine hydrochloride. The process of electrolysis using Frame Filter Press-electrolyzer, the contents of lead cathode, ruthenium / titanium or graphite anode and �50 ° C temperature, current density of 2 ~ 7A/dm2, anolyte 2 mol / L HCl aqueous solution of 20% liquid cathode cystine hydrochloride solution, cell voltage of 3 ~ 5V. Electrolysis finished, cathode by the bleaching solution, evaporation, condensation and crystallization was L-cysteine hydrochloride product yield less than 95%. The electrolysis process with high yield, good quality and simple operation, continuous, low power consumption characteristics, China has industrialized production years. The United States has developed the ammonia Electrolytic L-cystine, the electrolyte dried up after that the free L-cysteine process, the current density 30A/dm2, current efficiency and yield of nearly 100%.
