ICysteine iyi-amino acid enesibabule (ngemuva kwalokhu - i-AA). Ngokusho kweminye imithombo, umbandela lo awunakubuyiselwa endaweni. Leli gama ngokwezwi nezwi lisho ukuthi umzimba uyakwazi ukuhlanganisa i-cysteine ngaphansi kwezimo ezithile. Kodwa-ke, kuyenzeka ukuthi izinqolobane kufanele zigcwaliswe kusuka emithonjeni yangaphandle. Izici ezidinga i-cysteine eyengeziwe zibandakanya ukugula, ingcindezi, nokwanda komsebenzi wezemidlalo.
Ulwazi oluvamile
I-cysteine emzimbeni womuntu ibandakanyeka ku-glutathione ne-taurine synthesis. I-Taurine ibalulekile ekusebenzeni kwesistimu yezinzwa efanele. Kubalulekile ekulawuleni umfutho wegazi nasempilweni yokubuka. Isiza ukukhuphula ivolumu yemisipha futhi ishise amanoni amaningi omzimba.
Ukubaluleka kwe-glutathione akukwazi ukweqiswa. Ngaphandle kwayo, umsebenzi wokuzivikela kanye nokuvikelwa kwesistimu yezinzwa awucabangeki. Ukuntuleka kwalesi antioxidant kuvame ukuhambisana nezinqubo zokuguga nokusebenza okunciphile. Izithasiselo azikwazi ukubuyisa izinga lazo. Ukulungiswa kungenzeka kuphela ngokuba khona kwe-cysteine (C3H7NO2S).

UCysteine ubhekele umsebenzi ojwayelekile wemisipha. Kuyadingeka ngesikhathi sokuhlanganiswa kwama-T-lymphocyte ukuqinisa amasosha omzimba. Ingena esakhiweni sezinwele zomuntu ngamunye, ikhuphule ingxenye yesiphambano yomgodi. Futhi ingxenye ye-insulin. Uma kunesidingo, iyiguqula ibe ushukela futhi igcwalise umzimba ngomthamo owengeziwe wamandla. I-Antioxidant inomphumela omuhle emkhakheni wokugaya ukudla. Kuvikela futhi kuphulukise i-epithelium eyonakele egcizelele izitho zangaphakathi.
Ukuhlanganiswa kweCysteine
Ukuze kwenziwe i-cysteine, enye i-AA iyadingeka - i-methionine. Ukuhlanganiswa kwamakhemikhali amaningi kwalesi sakhi kuqhubeka ngokubamba iqhaza kwamavithamini amaningi nama-enzyme. Ukuntuleka kwanoma iyiphi yale miphumela "ekuphahlazekeni kwesistimu". Kwenzeka okufanayo nasenqubeni yokugula.
I-Serine ne-pyridoxine (B6) zisetshenziswa njengezinto zokusetshenziswa zokwenziwa kwe-cysteine. Ingxenye equkethe isulfure yakhiwa lapho kukhona i-hydrogen sulfide emzimbeni womuntu.
Izifo zesibindi kanye nokuphazamiseka kwemetabolism kuthinta kabi ukuhlanganiswa kwe-cysteine. Emizimbeni yezinsana, ukuxhumeka akwenziwa nhlobo. Lokhu kungenxa "yokubona kusengaphambili" kwemvelo. Ngakho-ke, njengazo zonke izinto ezibalulekile, ubisi lwebele (noma okunye okukushintshayo) kunikeza umntwana osanda kuzalwa nge-cysteine.
Izici eziwusizo ze-cysteine
I-AK isetshenziswa ekwelapheni izithiyo zamaphaphu neze-bronchial, ukuvimbela ukukhula kwamathumba anomdlavuza wamathumbu amakhulu. Kuyaziwa ukuthi i-cysteine ikhuthaza ukuqedwa kwe-metabolites eyingozi yotshwala, izidakamizwa futhi yandisa ukukhuthazela komzimba wabasubathi. Umsebenzi wokuvikela we-amino acid uthathwa ngaphansi kokuchayeka emisebeni.
I-cysteine nezifo
I-amino acid inciphisa kakhulu ushukela wegazi, ngenxa yalokho, ukuzwela kwe-insulin kunciphisa. Futhi, impahla evimbela i-cysteine ekuvuvukeni kwemithambo yegazi, eyenza sikwazi ukugwema izifo zenhliziyo ezinesifo sikashukela.
I-AK isiza ekunciphiseni ukubonakaliswa kwe-colitis. Ivimbela ukwakheka kwama-radicals wamahhala. Amandla we-antioxidant omzimba akhula kakhulu.
I-cysteine sekuyisikhathi eside yamukelwa ekwelashweni kweminye imithi njengekhambi elibhekiswe kokulandelayo:
- izifo zesistimu yenhliziyo;
- ukuvinjelwa kwamaphaphu kanye nokwenyuka kwamaphaphu;
- umkhuhlane;
- isifo sikashukela;
- ukuvuvukala kwama-etiologies ahlukahlukene;
- izifo ezihlangene;
- izifo zomgudu wamathumbu, njll.
Izinga lansuku zonke le-cysteine
Umthamo wansuku zonke we-AK ngesimo sezithako zokudla unikezwa emiyalweni. Izincomo zibophezelekile. Ukuthatha lesi sidakamizwa kudinga ukusetshenziswa komthamo omkhulu wamanzi.
Ngezinye izikhathi i-cysteine ingaba yingozi. Umthamo wansuku zonke ebangeni lama-2500-3000 mg ujwayelekile. Kubekezeleleke kahle futhi kunomphumela omuhle emzimbeni. Ukweqa umthamo (7 g noma ngaphezulu) kusongela ngomonakalo onobuthi futhi kuhlotshaniswa nemiphumela emibi.

Ngubani okhonjiswe i-cysteine?
Azikho izinkomba ezithile ze-cysteine eqenjini elithile labantu. Kuyasiza ngokulinganayo futhi kuyadingeka kuwo wonke umuntu. Noma kunjalo, abanye bayayidinga ngaphezu kwabanye. Isibonelo, abagijimi, umsebenzi wabo wokuzivocavoca, njengomthetho, udlula isilinganiso.
I-amino acid iyadingeka kubantu abagula kakhulu nabantu abanesizinda sokuzivikela komzimba esiphansi. Ukondleka okufanele ngomthamo owandisiwe we-AA kukhulisa ukumelana futhi kuthuthukise ukusebenza komzimba.
I-cysteine nayo iyadingeka kwiziguli ezine-HIV ne-AIDS. Kuyaziwa ukuthi kulezi zimo izivikelo zomzimba zehla kakhulu. Umphumela uba yimikhuhlane ejwayelekile, futhi nayo - ukulimala kwangaphakathi. Phakathi kwezinkomba eziqondile zokusetshenziswa kwe-cysteine kukhona izifo zezitho ze-ENT, inhliziyo nemithambo yegazi, izigaba zokuqala zezifo zamehlo (i-cataract).
Uyithatha nini i-cysteine ngokuqapha
Ukwamukelwa kwe-cysteine kwezinye izigaba zeziguli kufanele kwenziwe ngokuqapha okukhulu. Kumayelana nesifo sikashukela. Ukulinganiselwa kungenxa yekhono le-amino acid lokuthonya isenzo se-insulin. Okufanayo kusebenza ezigulini ezine-hypertension, i-thymus dysfunction, omama abancelisayo nabesifazane abakhulelwe. Isidingo se-cysteine supplementation asisebenzi kulabo abadla amaqanda, isinkwa, okusanhlamvu, u-anyanisi nogalikhi.
Umphumela oseceleni
Imiphumela emibi lapho uthatha i-amino acid ayivamile futhi ayibangeli monakalo omkhulu. Okuvame kakhulu: ukugaya isisu, uhudo, ukuhlanza, amajaqamba emathumbu, ikhanda elibuhlungu. Imvamisa zivela ngamanani amancane wokudla uketshezi. Zelashwa ngokunezimpawu, zisuswe ngokwandisa inani lamanzi okuphuza.
Yini okufanele uyibheke
Kwezinye izimo, ukuphathwa kwe-AK (ukungezwani komzimba) kuyaziwa. Umzimba "uphendula" ngendlela ekhethekile ekudleni i-cysteine, uphonsa umthamo orekhodiwe we-homocysteine egazini. Le hormone ikhiqizwa njalo ukuvikela ubuthi. Ukusabela okweqile kungabukeka njengokuphazamiseka, ukucindezeleka kokuphefumula, nokushaya kwenhliziyo okungavamile. Nganoma yikuphi ukubonakaliswa, kudingeka usizo oluphuthumayo lwezokwelapha.
Ukuhambisana nezinye izidakamizwa nezinto
Kuze kube manje, isayensi isihambele phambili kakhulu ekutadisheni i-cysteine. Umphumela wayo emzimbeni ubhekwa esimweni sokusetshenziswa isikhathi eside. Ukuhambisana kwe-AK nezinye izinto kuphakamisa ukukhathazeka okuthile.
Izithako zokudla eziqukethe i-cysteine ziyakwazi ukuxhumana nemithi. Isibonelo, ukuvimbela umsebenzi wezidakamizwa ekwelapheni i-tonsillitis, inhibitors, ama-enzyme. Ukunakekelwa okukhethekile kudinga ukungeniswa okufanayo kwama-amino acid kanye nama-immunosuppressants (Prednisolone, njll.). I-AK ayinconyelwe omama abahlengikazi nabakhulelwe.
Ukuze uthole inzuzo enkulu, kunconywa ukuthatha i-cysteine namavithamini C, E no-B6 (pyridoxine) ndawonye. Futhi i-calcium (Ca), isulfure (i-S) ne-selenium (Se), okuthuthukisa kakhulu ukusebenza kwe-AA.
Izimpawu zokweqisa ngokweqile nokushoda
Okuqukethwe okwandisiwe kwama-amino acid emzimbeni womuntu cishe njalo kuholela ekungezeleleni komzimba. Kanye nabo - ukucasuka, ukungasebenzi kwamathumbu kanye namahlule egazi.
Ukushoda kwe-AK kubonakala esimweni esingagculisi sezinzipho, isikhumba nezinwele. Ulwelwesi lwamafinyila lulahlekelwa ngokushesha umswakama, imifantu yakhona. Ukuphishekela isimo sokucindezeleka. Ngaphezu kwalokho, ukuntuleka kwe-cysteine kudala izifo zemithambo yegazi, ukungasebenzi kahle kohlelo lokugaya ukudla, ukwehla kokuzivikela komzimba, kanye nokwehla kokusebenza kobuchopho.
Imithombo
I-cysteine ikhona ekudleni ngokufakwa kwamaprotheni okwandisiwe. Lokhu kufaka phakathi:
- ubisi nazo zonke izinhlobo zenyama;
- amaqanda nenyama yenkukhu;
- imidumba;
- ukudla kwasolwandle;
- okusanhlamvu kwe-buckwheat;
- imbewu nezinhlamvu zamantongomane.
Ukuhlungwa okuphezulu kwe-cysteine kutholakala kumahlumela aseBrussels nase-broccoli, upelepele omnandi, u-anyanisi, amakhambi namakhanda egalikhi.

Ukupheka ukudla emazingeni okushisa aphezulu kuholela ekubhujisweni kwe-AA. Kodwa-ke, ukudla okuluhlaza akuxazululi inkinga. Uketshezi lwesisu kanye ne-microflora yamathumbu kuphazamisa kakhulu ukumuncwa kwe-cysteine.
Ifomu elilula kakhulu lokuthola i-AK ubisi whey. Kuyo inhlanganisela equkethe isulfure ivezwa njenge-cystine (i-block yamangqamuzana amabili). Ukungena emzimbeni, ibhulokhi iyawohloka futhi into iyangena. "Izitha" zenqubo yemvelo yi-pasteurization nokushisa okuphindaphindiwe. Ngakho-ke, ubisi oluthengwe esitolo alusoze lwaba umthombo ophelele wama-amino acid.
Isicelo sezimboni
Imboni yezokudla isebenzisa ngenkuthalo i-amino acid ngendlela yama-E920 supplements. Noma kunjalo, akusizi ngalutho emzimbeni.
Izithasiselo zemvelo futhi zihlanganisiwe. Zokwenziwa zikhiqizwa ezimbonini zamakhemikhali. I-amino acid yemvelo ishibhile. Kudinga uphaphe, uvolo noma izinwele. Lezi zicubu zine-keratin yemvelo, eyi-amino acid. I-cysteine eyenzeka ngokwemvelo itholakala ngenqubo ende. I-AK efunwayo ingumkhiqizo wokubola wezicubu zebhayoloji.
