Ingaruka ya seleniyumu
Ku bworozi n'ubworozi bw'inkoko
1. Kunoza imikorere yumusaruro nigipimo cyo guhindura ibiryo;
2. Kunoza imikorere yimyororokere;
3. Kunoza ubwiza bwinyama, amagi namata, no kunoza seleniyumu yibicuruzwa;
4. Kunoza intungamubiri za poroteyine;
5. Kunoza ubushobozi bwo kurwanya ihungabana ryinyamaswa;
6. Hindura mikorobe zo munda kugirango ubungabunge ubuzima bwo munda;
7. Kongera ubudahangarwa bw'inyamaswa…
Kuki seleniyumu kama iruta seleniyumu idasanzwe?
1. Nka nyongeramusaruro yo hanze, bioavailable ya selenium cysteine (SeCys) ntabwo yari hejuru ya sodium selenite. (Deagen et al., 1987, JNut.)
2. Inyamaswa ntizishobora guhuza selenoproteine ziva muri SeCys zidasanzwe.
3. Gukoresha neza SeCys mu nyamaswa biboneka rwose binyuze mu kongera guhindura no guhuza seleniyumu mu nzira ya metabolike no mu ngirabuzimafatizo.
4. Ikidendezi cya seleniyumu gikoreshwa mu kubika neza seleniyumu mu nyamaswa gishobora kuboneka gusa mugushyiramo synthesis ikurikirana ya proteine zirimo seleniyumu mu buryo bwa SeMet aho kuba molekile ya methionine, ariko SeCys ntishobora gukoresha iyi nzira ya synthesis.
Absorption inzira ya selenomethionine
Yinjizwa muburyo bumwe na methionine, yinjira mumaraso binyuze muri sisitemu yo kuvoma sodium muri duodenum.Kwishyira hamwe ntabwo bigira ingaruka ku kwinjiza.Kuberako methionine ari aside amine yingenzi, mubisanzwe iba yinjiye cyane.
Imikorere yibinyabuzima ya selenomethionine
1. Imikorere ya Antioxydeant: Selenium nicyo kigo gikora cya GPx, kandi imikorere yacyo ya antioxydeant igerwaho binyuze muri GPx na thioredoxin reductase (TrxR).Imikorere ya Antioxidant nigikorwa nyamukuru cya seleniyumu, nibindi bikorwa byibinyabuzima ahanini bishingiye kuriyi.
2. Guteza imbere gukura: Umubare munini wubushakashatsi wagaragaje ko kongeramo seleniyumu kama cyangwa seleniyumu idasanzwe mu ndyo bishobora kuzamura imikorere y’inkoko, ingurube, amatungo cyangwa amafi, nko kugabanya igipimo cy’ibiryo n’inyama no kongera ibiro bya buri munsi inyungu.
3. Kunoza imikorere yimyororokere: Ubushakashatsi bwerekanye ko seleniyumu ishobora kuzamura umuvuduko wintanga no kubara intanga mu masohoro, mugihe kubura seleniyumu bishobora kongera umuvuduko wintanga ngabo; kongeramo seleniyumu mumirire bishobora kongera ifumbire yimbuto, kongera umubare wimyanda, kwiyongera igipimo cy'umusaruro w'igi, kuzamura ubwiza bw'amagi no kongera uburemere bw'igi.
4. Kunoza ubwiza bwinyama: Okiside ya Lipide nikintu nyamukuru cyangirika kwubwiza bwinyama, imikorere ya seleniyumu antioxydeant nikintu nyamukuru kizamura ubwiza bwinyama.
5. Kwangiza: Ubushakashatsi bwerekanye ko seleniyumu ishobora kurwanya no kugabanya ingaruka z'ubumara bwa gurş, kadmium, arsenic, mercure nibindi bintu byangiza, fluoride na aflatoxine.
6. Indi mirimo: Byongeye kandi, seleniyumu igira uruhare runini mu kudahangarwa, kubika seleniyumu, gusohora imisemburo, ibikorwa bya enzyme igogora, n'ibindi.
