Kugwiritsa Ntchito Zogulitsa
1.Ascorbic acid, yomwe imadziwikanso kuti vitamini C, imagwira ntchito zosiyanasiyana zofunika m'thupi la munthu. Imakhala ngati antioxidant, cofactor for manyenzymatic reactions, coenzyme, wothandizira ufa wopangira ufa, antioxidant chakudya, metabolite chomera, chowunikira khungu, komanso chosungira mtundu wa chakudya.
2.Ascorbic acid ndi organic pawiri a gulu la unsaturated polyhydroxy alcohols. Ndi ketolactone yosungunuka m'madzi yokhala ndi mphete ya kaboni yokhala ndi mamembala asanu. Ili ndi mphamvu zochepetsera mphamvu chifukwa chomangika pawiri pa C2 ndi C3 ma carbons ndi magulu anayi a hydroxyl. Ascorbic acid amagwira ntchito ngati hydrogen kapena electron donor, ndikupangitsa kuti ikhale cofactor muzochitika zambiri za enzymatic.
3. Ngakhale kuti nyama zambiri zimatha kupanga ascorbic acid kuchokera ku shuga, anthu alibe enzyme yofunikira ndipo ayenera kuipeza kuchokera ku zakudya zawo. Zomwe zimafunikira tsiku lililonse pakudya kwa ascorbic acid zimasiyanasiyana, azimayi amafunikira 75 mg ndi amuna pafupifupi 90 mg. Ngakhale zipatso za citrus nthawi zambiri zimagwirizanitsidwa ndi ascorbic acid, zipatso zina, masamba, ndi nyama zimagwiranso ntchito ngati zakudya.
4. Ascorbic acid ndi chinthu chofunikira kwambiri chokhala ndi mamolekyu otsika kwambiri omwe amawongolera kuchuluka kwa mitundu ya okosijeni (ROS) ndikuwonjezera mphamvu ya ma antioxidants ena. Imagwira nawo gawo pakuwongolera kwa ROS pagawo lawo lopanga ndipo imapereka chofanana chochepetsera. Imalimbikitsa ntchito ya ma enzymes a antioxidant monga superoxide dismutase (SOD) ndipo ndiyofunikira pakupanga kolajeni.
Phukusi Ndi Kusungirako
Phukusi:
25kg / katoni ng'oma kapena monga zofunika zanu.
Ndemanga: Kupanga kwa Chemical ndi kukula kwake kumatha kukonzedwa ndi zomwe makasitomala amafuna
Posungira:
Olekanitsidwa ndi oxidants amphamvu ndi maziko amphamvu.Mayankho a ascorbic acid amatulutsidwa mofulumira mu mpweya ndi zamchere zamchere; mankhwala ayenera kutetezedwa mpweya ndi kuwala.
Chitetezo cha Chitetezo
Njira zodzitetezera kuti musagwire bwino
PALIBE moto wotseguka. Kusamalira pamalo abwino mpweya wokwanira. Valani zovala zoyenera zodzitetezera. Pewani kukhudzana ndi khungu ndi maso. Pewani kupanga fumbi ndi ma aerosols. Gwiritsani ntchito zida zopanda moto. Pewani moto woyambitsidwa ndi nthunzi ya electrostatic discharge.
