Mhedzisiro ye selenium
Zvekupfuya nehuku
1. Kuvandudza maitiro ekugadzira uye chiyero chekushandura chikafu;
2. Kuvandudza kuita kwekubereka;
3. Kuvandudza kunaka kwenyama, mazai nemukaka, uye kuvandudza selenium yehuwandu hwezvigadzirwa;
4. Kuvandudza mapuroteni emhuka;
5. Kuvandudza kugona kwemhuka kunopesana nekushushikana;
6. Kugadzirisa intestinal microorganisms kuchengetedza utano hwematumbo;
7. Kuvandudza kudzivirira kwemhuka…
Sei organic selenium iri nani pane inorganic selenium?
1. Sekuwedzera kwekunze, bioavailability ye selenium cysteine (SeCys) yakanga isiri yakakwirira kudarika sodium selenite. (Deagen et al., 1987, JNut.)
2. Mhuka haigoni kugadzira selenoprotein zvakananga kubva kune exogenous SeCys.
3. Kushandiswa kunobudirira kweSeCys mumhuka kunowanikwa zvachose kuburikidza nekugadzirisa zvakare uye synthesis ye selenium mumugwagwa wemagetsi uye mumasero.
4. Mvura yeselenium inoshandiswa kuchengetedza yakagadzikana ye selenium mumhuka inogona kuwanikwa chete nekuisa synthesis sequence ye selenium-ine mapuroteni nenzira yeSeMet panzvimbo yemethionine molecules, asi SeCys haigoni kushandisa iyi nzira yekubatanidza.
Nzira yekubvisa selenomethionine
Inotorwa nenzira imwechete se methionine, iyo inopinda muropa system kuburikidza ne sodium pumping system mu duodenum. Concentration yaitwa haina kukanganisa kunwa. Nekuti methionine yakakosha amino acid, inowanzo kunyudzwa zvakanyanya.
Biological mabasa e selenomethionine
1. Antioxidant basa: Selenium ndiyo inoshandiswa pakati peGPx, uye iyo antioxidant function inowanikwa kuburikidza neGPx uye thioredoxin reductase (TrxR). Antioxidant basa ndiro basa guru re selenium, uye mamwe mabasa ehupenyu anonyanya kuenderana neizvi.
2. Kukurudzira Kukura: Nhamba huru yezvidzidzo zvakaratidza kuti kuwedzera organic selenium kana inorganic selenium mukudya kunogona kuvandudza kushanda kwehuku, nguruve, ruminants kana hove, sekuderedza chiyero chekudya kune nyama uye kuwedzera uremu hwezuva nezuva. gain.
3. Kuvandudzwa kwekuita kubereka: Zvidzidzo zvakaratidza kuti selenium inogona kuvandudza kufamba kwembeu uye kuwedzera kwembeu mumbeu, nepo kushaikwa kwe selenium kunogona kuwedzera kukanganiswa kwembeu;Kuwedzera selenium mukudya kunogona kuwedzera fetiraiza yembeu, kuwedzera huwandu hwemarara, kuwedzera. chiyero chekugadzirwa kwezai, kunatsiridza ganda remazai uye kuwedzera uremu hwezai.
4. Kuvandudza hutano hwenyama: Lipid oxidation ndiyo chinhu chikuru chekuora kwehutano hwenyama, selenium antioxidant basa ndicho chinhu chikuru chekuvandudza nyama.
5. Kubvisa huturu: Zvidzidzo zvakaratidza kuti selenium inogona kupikisa uye kuderedza huturu hwemutobvu, cadmium, arsenic, mercury nezvimwe zvinokuvadza, fluoride uye aflatoxin.
6. Mamwe mabasa: Mukuwedzera, selenium inoita basa rinokosha mukudzivirira, selenium deposition, hormone secretion, digestive enzyme basa, nezvimwewo.
