Zinc feteleza raw

Zizindikiro zofala kwambiri zimaphatikizapo: Heptahtydrate sulfate, monohydrate zinc sulfate, herta clortide, zinc chrete, ndi nano zinc.

1.

- zinc sulfate: makhiristo kapena makhiristo oyera kapena oyera, magalamu, ndi ufa popanda fungo. Malo osungunuka: 100 ° C, ndi kukoma kwamphamvu. Kuchulukitsa: 1.957 g / cm³ (25 ° C). Kusungunuka mosavuta m'madzi, mankhwalawa amadzimadzi ndi acidic, komanso sungunuka pang'ono mu ethanol ndi glycerol.

- zinzi ndi shristate: kristalo yopanda utoto mu tetragonal system, hygroscopic, iyenera kusungidwa mumdima. Malo osungunuka: 36 ° C, malo owiritsa: 105 ° C, kachulukidwe: 2.065 g / cm³.

- zinc cloride: Malo osungunuka: 283 ° C, owiritsa: 732 ° C, kachulukidwe: 2.91 g / cm³. Imawoneka ngati ufa woyera wa crystalline, kusungunuka mosavuta m'madzi oyera, sothal ku methanol, ethanol, acetol, ndi etheloble, ndi soluble amadzimadzi a 395 pa 20 ° C.

- zinc oxide: Amadziwikanso kuti zinc oxide ufa, zoyera, kapena ufa woyera, ndi mafuta onunkhira okhala ndi ma encular zno ndi mol. Ndi loyera ndi mawonekedwe a zinn oxide. Axide wa zinc ndi wopanda m'madzi ndi Mowa, koma sungunuka mu acid, sodium hydroxide yankho, ndi ammonium chloride. Ndi oxide oxide ndi amatha kuchita ndi ma acid kapena zitsulo kuti apange mchere ndi madzi.

- EdTA zinc: sodium ethylenzensiamineacetetherthacetetherthacetetherthacetetherthacetetherthacetetherthacetetherthaacetetheaceteacetraacetraacetraacedracetraace zinc, Edta Cheade, Edta-ZN Mawonekedwe: oyera oyera.

- zinc citrate: Amadziwikanso kuti Citric acid zinc, zinc chikasu, kapena Tri-zinc litrate, amasungunuka pang'ono m'madzi; Sungunulani pamankhwala a acid a a acid ndi macheza a alkaline, omwe amapezeka ngati ufa wopanda utoto, wopanda ufa, komanso sungunuka pang'ono m'madzi, wokhala ndi kusungunuka kwa 2.6 g / l.

2. Ntchito za zinc mu chakudya

Zinc makamaka amagwira ntchito ngati gawo ndi woyambitsa ma enzymes, omwe amagwira ntchito yofunika kwambiri mu hydrolysis, njira redox, ndi kapangidwe ka mapu proteins a zinthu. Itha kulimbikitsa chitukuko cha ziwalo zoberekera mu mbewu ndikuwonjezera kukana kwawo kupsinjika. Zinc ndi gawo lofunikira pakupanga zomera, ndi zinc zokhudzana ndi 20-100 mg / kg. Pamene zinc Zomwe zimatsika m'munsi 20 mg / kg, zizindikiro za kuchepa kwa zinc kumatha kuchitika.

Zinc ndi gawo la ma enzyme osiyanasiyana, kuphatikiza superoxide dismusese, catalase, ndi carbonranthuli, ndipo mapuloteni, chakudya, ndi gawo lofunikira kwambiri pakukhalabe kukula kwamera. Mu anin metabolism, kapangidwe kake kamene kamasankhidwa, kumafuna zinc, ndi kuperewera kwa zinc kumatha kuchepetsa kuchitika kwa oubin mu mizu ya 30%. Mu protein metabolism, kuperewera kwa zinc kumabweretsa kukhazikika kwa RNA, kumakhudza kaphatikizidwe. Kafukufuku akuwonetsa kuti kugwiritsa ntchito feteleza wa zinc kumatha kukulitsa mapuloteni omwe amapezeka pampunga wolima ndi 6.9%.

Mu chakudya chamafuta, zinc imalimbikitsa chlorophyll kaphatikizidwe ndikuwonjezera kutsegulira kwa carbonic anhnthlizani ndi risphosphate carboxlase, kufalitsa carboxlase. Zinc imagwiranso ntchito yofunika kwambiri yopukutira kwa okosijeni muzomera ndikuwongolera kuthana ndi nkhawa zawo. Kuyambira koyambirira magawo a mpunga, kugwiritsa ntchito zinc kumatha kuchepetsa kwambiri kuwonongeka komwe kumachitika chifukwa cha kutentha kochepa kwa mphotho ya mpunga. Zinc kuchepa kwa mpunga makamaka nthawi ya mmera, kuwonekera ngati kukula kokhazikika ndikukula, ndipo kukula kwa masamba kumatembenuza, komanso mikangano ya bulauni, mawanga a bulauni omwe amawonekera masamba.
