Incazelo Yomkhiqizo:

I-L-cysteine, i-amino acid evame ukutholakala ezintweni eziphilayo. Ingenye ye-α-amino acid equkethe isulfure. Iphenduka onsomi (inemibala ngenxa ye-SH) phambi kwe-nitroprusside. Itholakala kumaprotheni amaningi kanye ne-glutathione. Ingenza izinhlanganisela ezingancibiliki ngama-ion ensimbi afana ne-Ag+, Hg+, ne-Cu+. i-mercaptide. Okusho ukuthi, i-RS-M', i-RSM"-SR (M', M" iyinsimbi e-monovalent ne-divalent, ngokulandelana).

Ifomula ye-molecular C3H7NO2S, isisindo samangqamuzana 121.16. Amakristalu angenambala. Incibilika emanzini, i-acetic acid ne-ammonia, ayincibiliki ku-ether, i-acetone, i-ethyl acetate, i-benzene, i-carbon disulfide ne-carbon tetrachloride. Ingafakwa i-oxidized ku-cystine ngomoya kuzixazululo ze-alkaline ezingathathi hlangothi nezibuthakathaka.

Ukusebenza kwe-L-Cysteine 99%:

1. Isetshenziswa kakhulu kwezokwelapha, izimonyo, ucwaningo lwe-biochemical, njll.

2. Isetshenziselwa isinkwa ukukhuthaza ukwakheka kwe-gluten, ukukhuthaza ukuvutshelwa, ukukhululwa kwesikhunta, nokuvimbela ukuguga.

3. Isetshenziswa kumajusi emvelo ukuvimbela i-oxidation kavithamini C futhi ivimbele ijusi ukuthi ingabansundu. Lo mkhiqizo unomphumela wokuqeda ubuthi futhi ungasetshenziselwa ubuthi be-acrylonitrile kanye nobuthi be-asidi enamakha.

4. Lo mkhiqizo uphinde ube nomthelela wokuvimbela ukulimala kwemisebe emzimbeni womuntu, futhi uwumuthi wokwelapha i-bronchitis, ikakhulukazi njengomuthi oqeda i-phlegm (osetshenziswa kakhulu njenge-acetyl L-cysteine methyl ester. Izimonyo ikakhulukazi asetshenziselwa ubuhle Amanzi, i-perm lotion, ukhilimu we-sunscreen, njll.
