No.1Isici esicacile, ingxenye eqondile ngenkathi sisabiza izindleko
I-L-selenomethionine yenziwa ngamakhemikhali, isakhi esiyingqayizivele, ukuhlanzeka okuphezulu (ngaphezu kwama-98%), umthombo wayo we-selenium u-100% uvela ku-L-selenomethionine.
Igama lekhemikhali: L-selenomethionine
Ifomula:C9H11NO2Se
Isisindo se-molecule: 196.11
Ukubukeka: Impushana Emhlophe Empunga, i-anti-caking, i-fluidity enhle

1. Umsebenzi we-Antioxidant: I-Selenium iyisikhungo esisebenzayo se-GPx, futhi umsebenzi wayo we-antioxidant wenziwa nge-GPx kanye ne-thioredoxin reductase (TrxR). Umsebenzi we-Antioxidant uwumsebenzi oyinhloko we-selenium, futhi eminye imisebenzi yezinto eziphilayo isekelwe kakhulu kulokhu.
2. Ukugqugquzelwa kokukhula: Izifundo eziningi ziye zafakazela ukuthi ukufaka i-selenium ephilayo noma i-selenium engaphili ekudleni kungathuthukisa ukusebenza kahle kwezinkukhu, izingulube, ezelusayo noma izinhlanzi, njengokunciphisa isilinganiso sokudla nenyama kanye nokwandisa isisindo sansuku zonke. zuza.
3. Ukusebenza okuthuthukisiwe kokuzala: Ucwaningo luye lwabonisa ukuthi i-selenium ingathuthukisa ukuhamba kwesidoda kanye nokubala kwesidoda esidodeni, kuyilapho ukuntuleka kwe-selenium kungakhuphula izinga lokungasebenzi kahle kwesidoda;Ukwengeza i-selenium ekudleni kungakhuphula izinga lokuvundisa kwezingulube, kwandise inani likadoti, kwande. izinga lokukhiqizwa kwamaqanda, ukuthuthukisa ikhwalithi yegobolondo leqanda futhi andise isisindo seqanda.
4. Thuthukisa ikhwalithi yenyama: I-lipid oxidation iyisici esiyinhloko sokuwohloka kwekhwalithi yenyama, umsebenzi we-selenium antioxidant iyisici esiyinhloko sokuthuthukisa ikhwalithi yenyama.
5. Ukukhipha ubuthi emzimbeni: Ucwaningo luye lwabonisa ukuthi i-selenium ingaphikisa futhi idambise imiphumela enobuthi yomthofu, i-cadmium, i-arsenic, i-mercury nezinye izakhi eziyingozi, i-fluoride ne-aflatoxin.
6. Eminye imisebenzi: Ngaphezu kwalokho, i-selenium idlala indima ebalulekile ekuvikelekeni komzimba, ukufakwa kwe-selenium, ukukhishwa kwe-hormone, umsebenzi we-enzyme yokugaya, njll.
Umthelela wesicelo ubonakala kakhulu kulezi zici ezine ezilandelayo:
1.Ukusebenza kokukhiqiza (ukuzuza kwesisindo sansuku zonke, ukusebenza kahle kokuguqulwa kokuphakelayo nezinye izinkomba).
2.Ukusebenza kokuzala (ukuhamba kwesidoda, izinga lokukhulelwa, usayizi wodoti ophilayo, isisindo sokuzalwa, njll.).
3.Inyama, iqanda kanye nekhwalithi yobisi (ikhwalithi yenyama - ukulahlekelwa ukuconsa, umbala wenyama, isisindo seqanda kanye nokufakwa kwe-selenium enyameni, amaqanda kanye nobisi).
4.Izinkomba ze-biochemical zegazi (izinga le-selenium yegazi kanye nomsebenzi we-gsh-px).
