1.Selenium ndi chigawo cha glutathione peroxidase, chomwe chimasunga ntchito ya ma cell membranes kudzera mu okosijeni ndikuwonjezera kupanga kwa endogenous antioxidants ndi lipid katundu wa mapuloteni.Kutenga nawo gawo pakutembenuka kwamphamvu, kumakhudza kagayidwe kazakudya, ndikuchita nawo gawo lofunikira kwambiri pakupanga emulsification ndi kuyamwa kwamafuta komanso kuyamwa kwa mavitamini osiyanasiyana.Nthawi yomweyo, imagwiranso ntchito popanga coenzyme A ndi coenzyme Q, zomwe zimakhudza magwiridwe antchito azinthu zina zama enzyme.Zimakhudza kagayidwe ka amino acid, kaphatikizidwe ka mapuloteni, kagayidwe kachakudya, komanso kagayidwe kazachilengedwe.Kuperewera kwa selenium m'thupi la ziweto ndi nkhuku kumatha kusokoneza kwambiri kukula kwawo, kakulidwe, ndi kubereka kwawo.Kuyeza kwa alkaloid.Kuyesa kameredwe ka mbeu.Chotsani mtundu wobiriwira popanga galasi.Kukonzekera kwachikuda glaze.
2. Sodium selenite imagwiritsidwa ntchito ngati chowonjezera cha selenium muzakudya.
3. Amagwiritsidwa ntchito ngati zowonjezera zakudya komanso zowonjezera chakudya.
4. Ntchito biochemical reagent kuyesa alkaloids ndi kumera mbewu.Amagwiritsidwa ntchito pokonzekera galasi lofiira ndi glaze yamitundu.
