Izakhiwo Zomzimba Nezamakhemikhali I-crystal emhlophe noma i-crystalline powder, iphunga, i-asidi, encibilika emanzini, i-ammonia, i-acetic acid, i-ethanol-soluble, i-acetone, i-ethyl acetate, i-benzene, i-carbon disulfide, i-carbon tetrachloride. Ukuzinza kwe-Acid, futhi kusisombululo esingathathi hlangothi noma esine-alkaline kulula ukuba i-air oxidation ibe yi-cystine, i-trace iron nama-ion ensimbi esindayo kungakhuthaza ukuxutshwa kwe-oxidation. I-hydrochloride yayo izinzile, ngakho-ke ngokuvamile yenziwa i-hydrochloride. I-L-cysteine ​​​​i-amino acid engabalulekile equkethe isulfure. Emzimbeni ophilayo, i-athomu ye-hydroxyl oxygen ye-serine ithathelwa indawo yi-athomu yesibabule ye-methionine futhi ihlanganiswe nge-thioether. I-L-cysteine ​​​​ingakwazi ukukhiqiza i-glutathione, ehilelekile ekunciphiseni inqubo yamaseli kanye ne-phospholipid metabolism esibindi, ingavikela amangqamuzana esibindi emonakalweni, futhi ingashukumisa umsebenzi we-hematopoietic, ukwandisa amangqamuzana egazi amhlophe, ikhuthaze ukulungiswa kwezilonda zesikhumba. I-mp yayo ingu-175 ℃, izinga lokushisa lokubola lingu-175 ℃, iphoyinti le-isoelectric ngu-5.07, [α]25D-16.5 (H2O), [α]25D 6.5 (5mol/L, HCl).

Isingeniso

Ukunambitheka kwe-asidi okuqinile, akunaphunga, kulandelela kuphela iphunga le-sulfite. Kuyi-amino acid esetshenziswa amangqamuzana ezicubu ezihlukahlukene ukuze avikele ezintweni eziyingozi futhi andise ubungqabavu ezilwaneni nasezitshalweni. Futhi ingenye yama-amino acid angaphezu kuka-20 akha amaprotheni, futhi iwukuphela kwe-amino acid ene-sulfhydryl (-SH) esebenzayo.
