Ingaruka za seleniyumu
Ku bworozi bw'amatungo n'inkoko
1. Kunoza umusaruro no guhindura ibiryo by'amatungo;
2. Kunoza imikorere yo kororoka;
3. Kunoza ubuziranenge bw'inyama, amagi n'amata, no kongera ingano ya seleniyumu mu bicuruzwa;
4. Kunoza imikorere ya poroteyine mu nyamaswa;
5. Kongera ubushobozi bwo kurwanya stress bw'amatungo;
6. Hindura udukoko two mu mara kugira ngo akomeze kugira ubuzima bwiza mu mara;
7. Kongera ubudahangarwa bw'umubiri ku nyamaswa…
Kuki selenium y’umwimerere iruta selenium idakomoka ku bimera?
1. Nk'inyongera yo hanze, ubushobozi bwa selenium cysteine (SeCys) bwo kubaho ntabwo bwari hejuru y'ubwa sodium selenite. (Deagen et al., 1987, JNut.)
2. Inyamaswa ntizishobora gukora selenoproteins mu buryo butaziguye zivuye muri SeCys zo hanze.
3. Gukoresha neza SeCys mu nyamaswa biboneka burundu binyuze mu kongera guhindura no gukora seleniyumu mu nzira y’imikorere y’umubiri no mu turemangingo.
4. Ikigega cya selenium gikoreshwa mu kubika selenium mu nyamaswa gishobora kuboneka gusa iyo umuntu ashyizemo uburyo bwo gukora poroteyine zirimo selenium mu buryo bwa SeMet aho gukoresha molekile za methionine, ariko SeCys ntishobora gukoresha ubu buryo bwo gukora.
Uburyo bwo kwinjiza selenomethionine
Inyuzwa mu buryo bumwe na methionine, yinjira mu maraso inyuze muri sisitemu yo gupompa sodiyumu muri duodenum. Ingano yayo ntabwo igira ingaruka ku inyuzwa. Kubera ko methionine ari aside amine y'ingenzi, akenshi inyuzwa cyane.
Imikorere ya selenomethionine mu binyabuzima
1. Imikorere ya Antioxydant: Selenium ni ihuriro rikora rya GPx, kandi imikorere yayo ya antioxydant ikorwa binyuze muri GPx na thioredoxin reductase (TrxR). Imikorere ya antioxydant ni imikorere nyamukuru ya selenium, kandi izindi nshingano za biyoloji zishingiye kuri ibi.
2. Guteza imbere imikurire: Ubushakashatsi bwinshi bwagaragaje ko kongeramo selenium y’umwimerere cyangwa selenium idakomoka ku bimera mu ndyo bishobora kongera imikurire y’inkoko, ingurube, amatungo y’inka cyangwa amafi, nko kugabanya igipimo cy’ibiryo by’inyama no kongera ibiro bya buri munsi.
3. Kunoza imikorere y'imyororokere: Ubushakashatsi bwagaragaje ko selenium ishobora kongera uburyo intanga zigenda neza n'umubare w'intanga mu masohoro, mu gihe kubura selenium bishobora kongera imiterere mibi y'intanga; Kongera selenium mu mirire bishobora kongera umuvuduko w'uburumbuke bw'ingore, kongera umubare w'imyanda, kongera umuvuduko w'umusaruro w'amagi, kongera ubwiza bw'ibishishwa by'amagi no kongera uburemere bw'igi.
4. Kongera ubuziranenge bw'inyama: Kugabanya ibinure mu mubiri ni cyo kintu cy'ingenzi gituma ubuziranenge bw'inyama bugabanuka, imikorere ya selenium irwanya uburozi ni yo mpamvu y'ingenzi ituma ubuziranenge bw'inyama burushaho kuba bwiza.
5. Gukuraho uburozi: Ubushakashatsi bwagaragaje ko selenium ishobora kurwanya no kugabanya ingaruka mbi za lead, cadmium, arsenic, mercure n'ibindi bintu byangiza, fluoride na aflatoxin.
6. Izindi nshingano: Byongeye kandi, selenium igira uruhare runini mu budahangarwa bw'umubiri, gushyira selenium mu mubiri, gusohora imisemburo, gukora enzymes zo mu gifu, n'ibindi.
