Umphumela we-selenium
Ukuzalanisa imfuyo kanye nezinkukhu
1. Thuthukisa ukusebenza kokukhiqiza kanye nezinga lokuguqulwa kokudla;
2. Thuthukisa ukusebenza kokuzala kabusha;
3. Thuthukisa ikhwalithi yenyama, amaqanda nobisi, futhi uthuthukise okuqukethwe kwe-selenium emikhiqizweni;
4. Thuthukisa ukwakheka kwamaprotheni ezilwane;
5. Thuthukisa ikhono lezilwane lokulwa nokucindezeleka;
6. Lungisa amagciwane amathumbu ukuze kugcinwe impilo yamathumbu;
7. Thuthukisa amasosha omzimba ezilwaneni…
Kungani i-selenium ephilayo ingcono kune-selenium engaphili?
1. Njengesengezo sangaphandle, ukutholakala kwe-selenium cysteine (SeCys) kwakungephezulu kunokwe-sodium selenite. (Deagen et al., 1987, JNut.)
2. Izilwane azikwazi ukukhiqiza ama-selenoprotein ngqo kusuka kuma-SeCy angaphandle.
3. Ukusetshenziswa okuphumelelayo kwe-SeCys ezilwaneni kutholakala ngokuphelele ngokuguqulwa kabusha kanye nokuhlanganiswa kwe-selenium endleleni ye-metabolic kanye nasemaseli.
4. Idamu le-selenium elisetshenziselwa ukugcina i-selenium ezilwaneni lingatholakala kuphela ngokufaka ukulandelana kokwenziwa kwamaprotheni aqukethe i-selenium ngesimo se-SeMet esikhundleni sama-molecule e-methionine, kodwa ama-SeCy awakwazi ukusebenzisa le ndlela yokwenziwa.
Indlela yokumunca i-selenomethionine
Imuncwa ngendlela efanayo ne-methionine, engena ohlelweni lwegazi ngesistimu yokupompa i-sodium ku-duodenum. Ukuhlushwa akukuthinti ukumuncwa. Ngenxa yokuthi i-methionine iyi-amino acid ebalulekile, ivame ukumuncwa kakhulu.
Imisebenzi yezinto eziphilayo ye-selenomethionine
1. Umsebenzi we-Antioxidant: I-Selenium iyisikhungo esisebenzayo se-GPx, futhi umsebenzi wayo we-antioxidant ubonakala nge-GPx kanye ne-thioredoxin reductase (TrxR). Umsebenzi we-Antioxidant uwumsebenzi oyinhloko we-selenium, kanti eminye imisebenzi yezinto eziphilayo isekelwe kakhulu kulokhu.
2. Ukukhuthazwa kokukhula: Inani elikhulu lezifundo liye lafakazela ukuthi ukwengeza i-selenium ephilayo noma i-selenium engaphilayo ekudleni kungathuthukisa ukusebenza kokukhula kwezinkukhu, izingulube, izilwane ezelusayo noma izinhlanzi, njengokunciphisa isilinganiso sokudla kwenyama nokwandisa inzuzo yesisindo yansuku zonke.
3. Ukusebenza okuthuthukisiwe kokuzala: Izifundo zikhombisile ukuthi i-selenium ingathuthukisa ukuhamba kwesidoda kanye nenani lesidoda esidodeni, kanti ukuntuleka kwe-selenium kungandisa izinga lokukhubazeka kwesidoda; Ukwengeza i-selenium ekudleni kungandisa izinga lokuvundisa kwezinsikazi, kwandise inani lezinsana, kwandise izinga lokukhiqizwa kwamaqanda, kwandise ikhwalithi yamagobolondo eqanda futhi kwandise isisindo seqanda.
4. Thuthukisa ikhwalithi yenyama: Ukushiswa kwamafutha emzimbeni kuyisici esiyinhloko sokuwohloka kwekhwalithi yenyama, umsebenzi we-selenium antioxidant uyisici esiyinhloko sokuthuthukisa ikhwalithi yenyama.
5. Ukususa ubuthi emzimbeni: Izifundo zikhombisile ukuthi i-selenium ingadala ukuphikisana futhi inciphise imiphumela enobuthi ye-lead, i-cadmium, i-arsenic, i-mercury nezinye izinto eziyingozi, i-fluoride kanye ne-aflatoxin.
6. Eminye imisebenzi: Ngaphezu kwalokho, i-selenium idlala indima ebalulekile ekuvikeleni amasosha omzimba, ukugcinwa kwe-selenium, ukukhishwa kwama-hormone, umsebenzi we-enzyme yokugaya ukudla, njll.
