TSISTEIN (Cysteinum) (See also Penitsillamin.) .

     L-Cysteine, or L-1- amino-2- merkaptopropionovaya acid.

     The white crystalline powder with low specific odor. Soluble in water. Aqueous solutions nestoyki, oxidizing oxygen from air deposition of sludge (insoluble tsistin); Situated in the high temperature sterilization.

     Cysteine is: zamenimoy amino acids; May synthesized in the body of methionine. However, in the absence of methionine, or in violation of turning methionine in Cysteine, the lack of amino acids that can disrupt metabolism in the body.

     A characteristic feature of the chemical is a cysteine in its molecules sulfgidrilnoy Group (-SH). The group cysteine (See also Unitiol) very reaktsionnosposobna; It can oxidize spontaneously and under the influence of special enzymes; Formed with products like himself Cysteine, transaminirovaniya involved in the reaction. Cysteine is also involved in the exchange of sulfur in the body. Fission cysteine influenced desulfogidrazy results in pirovinogradnoy acid and hydrogen sulphide. Under certain conditions Cysteine readily acknowledges hydrogen, and then two cysteine molecules formed through disulfidnuyu communications (-S-S-) tsistin new amino acids. Cysteine and tsistin can easily become each other; This shift represents device recovery process.

     Light turning sulfgidrilnyh groups cysteine in disulfidnuyu link cysteine and reversibility of the reactions play an important role in regulation of the exchange.

     There is evidence that Cysteine involved in the exchange of substances eye lens, and changes in cataract, associated with the content in the lens of the amino acids. For this reason, Cysteine invited to apply for delaying cataract development and enlightenment lens, with the primary form of age, miopaticheskoy, radiation and kontuzionnoy cataracts. In the back of aluminium cataract effect not observed.

     Assign electrophoresis 5% aqueous solution cysteine (with the negative pole). Solution produce directly to the use of distilled water. Duration first treatment (8 min) daily up to 2 minutes and bring up to 20 minutes. The course of treatment procedures of 40 g.

     Sometimes using Cysteine as 2% solution of distilled water for eye vannochek (without electrophoresis).

     As Cysteine nestoek and solutions should be applied immediately after cooking, prefer a special eye drops used drug vitsein (cm), containing Cysteine in combination with other substances.

     Application cysteine counter promotions vnutriglaznogo pressure. It should not be used in aluminium cataract.

     Form release: powder in a densely ukuporennyh banks of 10 g.

     Storage: a dry, protected from light, cool place. Complete solutions to store no more than 4 hours
