Cov nyhuv ntawm selenium
Rau kev yug tsiaj thiab yug qaib
1. Txhim kho kev ua tau zoo ntawm kev tsim khoom thiab kev hloov pauv ntawm cov khoom noj;
2. Txhim kho kev ua tau zoo ntawm kev yug me nyuam;
3. Txhim kho qhov zoo ntawm nqaij, qe thiab mis nyuj, thiab txhim kho cov ntsiab lus selenium ntawm cov khoom;
4. Txhim kho cov protein synthesis ntawm tsiaj txhu;
5. Txhim kho lub peev xwm tiv thaiv kev ntxhov siab ntawm cov tsiaj;
6. Kho cov kab mob hauv plab kom tswj tau kev noj qab haus huv ntawm plab;
7. Txhim kho kev tiv thaiv kab mob ntawm tsiaj txhu ...
Vim li cas cov organic selenium zoo dua li cov inorganic selenium?
1. Ua ib qho khoom siv sab nraud, qhov bioavailability ntawm selenium cysteine (SeCys) tsis siab dua li ntawm sodium selenite. (Deagen et al., 1987, JNut.)
2. Cov tsiaj txhu tsis tuaj yeem tsim cov selenoproteins ncaj qha los ntawm exogenous SeCys.
3. Kev siv SeCys zoo hauv cov tsiaj txhu tau txais tag nrho los ntawm kev hloov pauv thiab kev tsim cov selenium hauv txoj kev zom zaub mov thiab hauv cov hlwb.
4. Lub pas dej selenium siv rau kev khaws cia selenium ruaj khov hauv cov tsiaj tsuas yog tau los ntawm kev ntxig cov txheej txheem tsim cov protein uas muaj selenium hauv daim ntawv ntawm SeMet es tsis txhob siv cov molecules methionine, tab sis SeCys siv tsis tau txoj kev tsim cov tshuaj no.
Txoj kev nqus ntawm selenomethionine
Nws raug nqus tau tib yam li methionine, uas nkag mus rau hauv cov ntshav los ntawm lub cev sodium pumping hauv duodenum. Qhov concentration tsis cuam tshuam rau kev nqus. Vim tias methionine yog ib qho amino acid tseem ceeb, nws feem ntau raug nqus tau zoo heev.
Cov haujlwm ntawm selenomethionine
1. Kev ua haujlwm ntawm cov tshuaj antioxidant: Selenium yog lub hauv paus tseem ceeb ntawm GPx, thiab nws cov haujlwm antioxidant tau ua tiav los ntawm GPx thiab thioredoxin reductase (TrxR). Kev ua haujlwm ntawm cov tshuaj antioxidant yog lub luag haujlwm tseem ceeb ntawm selenium, thiab lwm yam haujlwm ntawm lub cev feem ntau yog raws li qhov no.
2. Kev txhawb nqa kev loj hlob: Muaj ntau txoj kev tshawb fawb tau ua pov thawj tias kev ntxiv cov organic selenium lossis inorganic selenium rau hauv cov zaub mov tuaj yeem txhim kho kev loj hlob ntawm cov nqaij qaib, npua, ruminants lossis ntses, xws li txo qhov piv ntawm cov khoom noj rau nqaij thiab ua rau qhov hnyav nce txhua hnub.
3. Kev ua tau zoo dua ntawm kev yug me nyuam: Cov kev tshawb fawb tau qhia tias selenium tuaj yeem txhim kho kev txav mus los ntawm cov phev thiab cov phev hauv cov phev, thaum selenium tsis txaus tuaj yeem ua rau cov phev tsis zoo; Ntxiv selenium rau hauv cov zaub mov tuaj yeem ua rau cov npua cog qoob loo ntau dua, nce tus naj npawb ntawm cov quav, nce tus nqi ntawm cov qe tsim tawm, txhim kho qhov zoo ntawm cov plhaub qe thiab ua rau cov qe hnyav dua.
4. Txhim kho qhov zoo ntawm nqaij: Lipid oxidation yog qhov tseem ceeb tshaj plaws ntawm kev puas tsuaj ntawm nqaij, selenium antioxidant muaj nuj nqi yog qhov tseem ceeb tshaj plaws los txhim kho qhov zoo ntawm nqaij.
5. Kev Tshem Tawm Cov Tshuaj Lom: Cov kev tshawb fawb tau qhia tias selenium tuaj yeem tawm tsam thiab txo cov teebmeem lom ntawm cov hlau lead, cadmium, arsenic, mercury thiab lwm yam khoom lom, fluoride thiab aflatoxin.
6. Lwm yam haujlwm: Tsis tas li ntawd, selenium ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kab mob, selenium deposition, hormone secretion, digestive enzyme activity, thiab lwm yam.
