1. Kev Lag Luam Khoom Noj (Qhov Chaw Siv Tseem Ceeb)
Cov Khoom Siv Txhim Kho Hmoov thiab Cov Khoom Noj Ci: Qhov no yog qhov kev siv loj tshaj plaws ntawm L-cysteine. Ua tus neeg sawv cev txo qis, nws tuaj yeem rhuav tshem cov disulfide bonds hauv cov protein hauv cov khob cij, txo qhov gluten lub zog thiab elasticity ntawm cov khob cij, yog li:
Ua kom lub sijhawm kneading luv dua thiab ua kom cov khoom tsim tau zoo dua.
Txhim kho qhov ua kom cov khob noom cookie nthuav dav, ua kom yooj yim rau kev ua haujlwm siv tshuab (xws li ua ramen thiab biscuits).
Ua kom cov qauv qhob cij sib npaug thiab loj dua.
Cov Tshuaj Txhim Kho Qab Ntuj: Siv rau hauv kev tsim cov tsw qab rau nqaij, khoom noj hiav txwv, thiab mov ci, tsim cov ntxhiab tsw qab "nqaij".
Tshuaj tua kab mob antioxidant: Vim nws cov khoom antioxidant, L-Cysteine tuaj yeem siv rau hauv cov khoom noj xws li kua txiv hmab txiv ntoo thiab mis hmoov kom tiv thaiv kev puas tsuaj ntawm vitamin C thiab kev oxidation ntawm cov rog, ua kom lub txee ntev dua.
Cov Khoom Noj Khoom Haus Ntxiv: Ntxiv rau cov khoom noj uas tsis muaj methionine (lwm yam amino acid tseem ceeb) kom txhim kho lawv cov txiaj ntsig kev noj haus.
2. Kev Ua Lag Luam Tshuaj
Kev Tiv Thaiv Kab Mob Siab thiab Kev Tshem Tawm Cov Tshuaj Lom: Ib qho khoom siv tseem ceeb rau kev tsim cov glutathione. Glutathione yog ib qho ntawm cov tshuaj antioxidants thiab cov tshuaj lom tseem ceeb tshaj plaws hauv tib neeg lub cev. L-Cysteine pab kab mob siab rhuav tshem cov tshuaj lom thiab kho cov kab mob siab uas tshwm sim los ntawm kev siv tshuaj, kab mob siab cawv, thiab lwm yam.
Tshuaj Expectorant thiab Antitussive: L-Cysteine tuaj yeem rhuav tshem cov disulfide bonds hauv mucin hauv cov hnoos qeev, txo cov hnoos qeev viscosity thiab ua rau nws yooj yim dua rau hnoos tawm. Nws feem ntau yog siv ua kev kho mob ntxiv rau mob khaub thuas thiab mob ntsws ntev.
Kev tiv thaiv hluav taws xob: L-Cysteine txo qhov kev puas tsuaj rau lub cev los ntawm kev kho hluav taws xob.
Txhawb kev kho qhov txhab.
3. Tshuaj pleev ib ce thiab kev saib xyuas tus kheej
Ua kom tawv nqaij dawb thiab tiv thaiv kev oxidation: Ua ib qho ua ntej rau glutathione, nws tuaj yeem tiv thaiv kev tsim melanin, yog li ua tiav cov teebmeem dawb thiab ua rau cov tawv nqaij ploj mus. L-Cysteine tso cov free radicals thiab qeeb qeeb kev laus ntawm daim tawv nqaij.
Kev saib xyuas plaub hau: L-Cysteine yog ib qho ntawm cov amino acids tseem ceeb hauv cov plaub hau keratin. Ntxiv nws rau hauv cov tshuaj zawv plaub hau thiab cov tshuaj pleev plaub hau tuaj yeem pab kho cov plaub hau puas thiab tswj nws lub zog thiab elasticity.
Cov neeg sawv cev perming: Hauv cov neeg sawv cev perming mos mos, nws tuaj yeem pab rhuav thiab rov tsim cov disulfide bonds hauv cov plaub hau, txo kev puas tsuaj.
4. Cov khoom noj ntxiv
Cov no raug ntxiv rau hauv cov khoom noj ua cov amino acids tseem ceeb los txhawb kev loj hlob ntawm cov tsiaj txhu thiab cov nqaij qaib thiab txhim kho kev siv cov khoom noj.
1. Kev sib haum xeeb thiab kev nqus tau: Ua ib qho amino acid uas tshwm sim hauv ntuj, nws yooj yim nqus thiab siv los ntawm lub cev, nrog kev nyab xeeb siab.
2. Kev yaj dej tau yooj yim: Yooj yim ntxiv thiab siv rau hauv ntau yam dej-raws li systems.
3. Kev Ua Haujlwm Ntau Yam: Kev sib xyaw ua ke ntawm cov haujlwm ntawm tus neeg txo qis, antioxidant, khoom noj khoom haus ntxiv, tshuaj tua kab mob, expectorant, thiab cov khoom xyaw ua kom dawb, nws cov ntawv thov hla ntau yam lag luam.
