Ectoin yog dab tsi?
Ectoin yog ib qho amino acid derivative, ib qho khoom xyaw ua haujlwm ntau yam uas yog ib feem ntawm cov enzyme fraction loj heev, uas tiv thaiv thiab tiv thaiv kev puas tsuaj ntawm cov cell, thiab tseem muab cov teebmeem kho thiab rov ua dua tshiab rau cov cell laus, nrog rau cov tawv nqaij ntxhov siab thiab khaus ib ntus.
Nws tiv thaiv cov kab mob me me thiab cov nroj tsuag los ntawm cov xwm txheej txaus ntshai thiab hnyav ntawm cov chaw nyob xws li cov pas dej ntsev, cov dej kub, dej khov, dej hiav txwv tob lossis suab puam.
Keeb kwm ntawm Ectoin yog dab tsi?
Los ntawm cov suab puam kub heev ntawm tebchaws Iziv lossis "daim iav ntawm lub ntuj", cov dej ntsev Uyuni hauv Bolivia.
Hauv cov suab puam no, muaj cov pas dej ntsev uas muaj ntsev ntau heev. Qhov no yuav luag yog qhov chaw nkaum rau txoj sia, vim tias tsis yog qhov kub thiab txias xwb, tab sis kuj muaj ntsev ntau heev uas txhua yam tsiaj txhu, loj lossis me, uas tsis muaj peev xwm "khaws dej" yuav tuag sai sai los ntawm lub hnub, raug cua kub qhuav thiab raug dej ntsev ntau dhau tuag.
Tiamsis muaj ib tug kab mob me me uas muaj peev xwm nyob tau ntawm no thiab nyob kaj siab lug mus ib txhis. Cov neeg tshawb nrhiav tau muab cov kab mob me me no rau cov kws tshawb fawb, thiab cov kws tshawb fawb tau pom "Ectoin" hauv tus tsiaj no.
Cov teebmeem ntawm Ectoin yog dab tsi?
(1) Kev ua kom noo, kev xauv dej thiab kev ua kom noo noo:
Los ntawm kev ua kom lub tawv nqaij ruaj khov thiab kho thiab tswj cov dej noo ntawm daim tawv nqaij, nws txo qhov kev poob dej ntawm daim tawv nqaij thiab ua rau daim tawv nqaij noo ntxiv. Ectoin yog ib yam khoom tseem ceeb los tswj qhov sib npaug ntawm osmotic pressure, thiab nws cov qauv molecular tshwj xeeb ua rau nws muaj peev xwm ua kom cov dej sib xyaw ua ke; ib lub molecule ntawm Ectoin tuaj yeem ua rau plaub lossis tsib lub molecule dej sib xyaw ua ke, uas tuaj yeem tsim cov dej dawb hauv lub cell, txo qhov evaporation ntawm dej hauv daim tawv nqaij, thiab ua rau daim tawv nqaij noo thiab tuav dej tau zoo dua tas li.
(2) Kev rho tawm thiab kev tiv thaiv:
Ectoin tuaj yeem tsim lub plhaub tiv thaiv nyob ib puag ncig cov cell, enzymes, proteins thiab lwm yam biomolecules, zoo li "lub tsho me me", uas tuaj yeem txo qhov kev cuam tshuam ntawm cov teeb ultraviolet muaj zog (uas yog ib qho ntawm kev puas tsuaj rau daim tawv nqaij uas peb tuaj yeem xav txog) nyob rau hauv qhov xwm txheej ntawm salinity siab, yog li qhov kev puas tsuaj los ntawm cov teeb ultraviolet tuaj yeem tiv thaiv tau. Yog li ntawd, "cov pa oxygen reactive" lossis "free radicals" los ntawm cov teeb UV, uas tuaj yeem tawm tsam DNA lossis cov protein ncaj qha, raug thaiv tawm. Vim muaj lub plhaub tiv thaiv, cov cell tawv nqaij zoo ib yam li "armed" up, nrog "kev tiv thaiv" zoo dua, tsis tshua muaj peev xwm raug txhawb los ntawm cov yam ntxwv sab nraud los txhawb, yog li txo qhov o thiab kev puas tsuaj teb.
(3) Kev kho thiab kev tsim dua tshiab:
Ectoin tuaj yeem txhim kho lub peev xwm tiv thaiv kab mob ntawm cov tawv nqaij, thiab muaj cov txiaj ntsig zoo rau ntau yam kev puas tsuaj rau cov nqaij tawv, tshem tawm pob txuv, pob txuv, qhov tsis zoo me me tom qab tshem tawm cov mole, tev tawv nqaij thiab liab tom qab tev tawv nqaij, nrog rau kev kub hnyiab tawv nqaij los ntawm kev siv cov kua txiv hmab txiv ntoo thiab lwm yam kub hnyiab tawv nqaij, thiab kho cov epidermal puas tsuaj tom qab sib tsoo, thiab lwm yam. Nws txhim kho qhov nyias nyias ntawm daim tawv nqaij, qhov ntxhib, qhov txhab thiab lwm yam mob tsis zoo, thiab rov qab ua kom daim tawv nqaij du thiab ci ntsa iab, thiab kav ntev thiab ruaj khov. Kev ruaj khov ntawm daim tawv nqaij tiv thaiv kab mob kav ntev thiab ruaj khov.
(4) Tiv thaiv daim tawv nqaij thaiv:
Tom qab kev tshawb fawb tas mus li thiab tob tob los ntawm cov kws tshawb fawb, nws pom tias cov khoom xyaw no tsis yog tsuas yog muaj zog tiv thaiv kev ntxhov siab thiab lub zog kho zoo xwb, tab sis kuj tau ua pov thawj tias yog cov khoom xyaw zoo rau kev kho lub txheej tawv nqaij. Thaum lub txheej tawv nqaij puas lawm, lub peev xwm nqus ntawm daim tawv nqaij tsis muaj zog heev ua rau muaj mob tsis zoo. Ectoin tsim ib txheej tiv thaiv dej muaj zog hauv daim tawv nqaij, uas ua rau lub cev muaj zog thiab rov qab ua haujlwm ntawm tes, ua kom lub txheej tawv nqaij ruaj khov, thiab rov qab kho thiab tswj cov dej noo. Nws tuaj yeem pab daim tawv nqaij kaw cov dej noo thiab tswj ib puag ncig zoo rau kev loj hlob ntawm tes, tib lub sijhawm nws kuj pab kho lub txheej tawv nqaij thiab ua kom daim tawv nqaij noj qab haus huv thiab muaj dej txaus.
