Zotsatira za selenium
Zoweta ziweto ndi nkhuku
1. Kupititsa patsogolo kagwiridwe ka ntchito ndi kusintha kwa chakudya;
2. Kupititsa patsogolo ntchito zobereketsa;
3. Kupititsa patsogolo ubwino wa nyama, mazira ndi mkaka, ndi kusintha selenium zomwe zili muzinthu;
4. Kupititsa patsogolo kaphatikizidwe ka mapuloteni a nyama;
5. Kupititsa patsogolo luso loletsa kupsinjika kwa nyama;
6. Sinthani tizilombo ta m'matumbo kuti tisunge thanzi la m'mimba;
7. Kupititsa patsogolo chitetezo cha ziweto ...
Chifukwa chiyani organic selenium ndiyabwino kuposa selenium?
1. Monga chowonjezera chakunja, bioavailability ya selenium cysteine (SeCys) sichinali yapamwamba kuposa sodium selenite. (Deagen et al., 1987, JNut.)
2. Nyama sizingathe kupanga selenoproteins mwachindunji kuchokera ku SeCys yachilendo.
3. Kugwiritsa ntchito bwino kwa SeCys mu zinyama kumapezedwa kwathunthu kupyolera mu kusinthanso ndi kaphatikizidwe ka selenium mu njira ya kagayidwe kachakudya ndi m'maselo.
4. Damu la selenium lomwe limagwiritsidwa ntchito kuti likhale lokhazikika la selenium mu zinyama likhoza kupezedwa mwa kuyika ndondomeko ya kaphatikizidwe ka mapuloteni okhala ndi selenium mu mawonekedwe a SeMet m'malo mwa mamolekyu a methionine, koma SeCys sangathe kugwiritsa ntchito njirayi.
Njira yoyamwitsa ya selenomethionine
Imatengedwa mofanana ndi methionine, yomwe imalowa m'magazi kudzera mu njira yopopa sodium mu duodenum. Kukhazikika kwake sikukhudza kuyamwa. Chifukwa methionine ndi amino acid wofunikira, nthawi zambiri imayamwa kwambiri.
Biological ntchito selenomethionine
1. Ntchito ya Antioxidant: Selenium ndi malo ogwira ntchito a GPx, ndipo ntchito yake ya antioxidant imazindikiridwa kudzera mu GPx ndi thioredoxin reductase (TrxR). Ntchito ya Antioxidant ndiyo ntchito yayikulu ya selenium, ndipo ntchito zina zachilengedwe zimatengera izi.
2. Kupititsa patsogolo Kukula: Kafukufuku wambiri watsimikizira kuti kuwonjezera organic selenium kapena selenium muzakudya kumatha kupititsa patsogolo kukula kwa nkhuku, nkhumba, zoweta kapena nsomba, monga kuchepetsa chiŵerengero cha chakudya ndi nyama ndikuwonjezera kulemera kwa tsiku ndi tsiku. phindu.
3. Kupititsa patsogolo ntchito zoberekera: Kafukufuku wasonyeza kuti selenium ingathandize kuti umuna uyambe kuyenda komanso kuchuluka kwa umuna mu umuna, pamene kuchepa kwa selenium kungapangitse umuna wa malformation; Kuwonjezera selenium m'zakudya kungapangitse umuna wa nkhumba, kuwonjezera kuchuluka kwa zinyalala, kuwonjezeka. mlingo wa kupanga dzira, kusintha chigoba cha dzira ndikuwonjezera kulemera kwa dzira.
4. Kupititsa patsogolo khalidwe la nyama: Lipid oxidation ndiye chinthu chachikulu cha kuwonongeka kwa khalidwe la nyama, selenium antioxidant ntchito ndiyo chinthu chachikulu chothandizira kuti nyama ikhale yabwino.
5. Kuchotsa poizoni: Kafukufuku wasonyeza kuti selenium imatha kutsutsa ndi kuchepetsa zotsatira za poizoni za lead, cadmium, arsenic, mercury ndi zinthu zina zovulaza, fluoride ndi aflatoxin.
6. Ntchito zina: Kuphatikiza apo, selenium imagwira ntchito yofunika kwambiri pakuteteza chitetezo, selenium deposition, hormone secretion, digestive enzyme ntchito, etc.
