Kushandisa Zvigadzirwa
1.Ascorbic acid, inozivikanwawo sevhitamini C, inoshandisa mabasa akasiyana-siyana anokosha mumuviri womunhu. Inoshanda se antioxidant, cofactor kune akawanda enzymatic reactions, coenzyme, furawa yekurapa agent, chikafu che antioxidant, chirimwa che metabolite, ganda-chiedza cheganda, uye chikafu chekuchengetedza ruvara.
2.Ascorbic acid is an organic compound yeboka reunsaturated polyhydroxy alcohols. Iketolactone inonyungudika nemvura ine mhete yekabhoni ine nhengo shanu. Iyo ine yakasimba yekudzikisa zvivakwa nekuda kwekaviri zvisungo paC2 neC3 carbons uye mana hydroxyl mapoka. Ascorbic asidhi inoshanda sehydrogen kana electron donor, ichiita kuti ive cofactor mune dzakawanda enzymatic reaction.
3. Nepo mhuka zhinji dzinoyamwisa dzichigona kugadzira ascorbic acid kubva muglucose, vanhu havana enzyme inodiwa uye vanofanirwa kuiwana kubva mukudya kwavo. Zvinodiwa zvezuva nezuva zvekudya kweascorbic acid zvinosiyana, nevakadzi vanoda kutenderedza 75 mg uye varume vakatenderedza 90 mg. Kunyange zvazvo michero ye citrus inowanzobatanidzwa ne ascorbic acid, mimwe michero, miriwo, uye nyama inoshandawo sezvokudya.
4. Ascorbic acid yakakosha yakaderera-molecular-weight antioxidant iyo inodzora mazinga eiyo reactive oxygen marudzi (ROS) uye inowedzera kushanda kwemamwe antioxidants. Iyo inotora chikamu muROS mutemo padanho ravo rekugadzira uye inopa imwechete yekudzikisa yakaenzana. Inosimudzira basa re antioxidant enzymes senge superoxide dismutase (SOD) uye yakakosha kune collagen synthesis.
Package Uye Kuchengeta
Package:
25kg/carton dhiramu kana sezvinodiwa zvako.
Remark: Kemikari kuumbwa uye saizi inogona kuvandudzwa nezvinodiwa nevatengi
Kuchengeta:
Yakaparadzaniswa kubva kune yakasimba oxidants uye mabhesi akasimba.Solutions of ascorbic acid inokurumidza kuiswa mumhepo uye mune alkaline media; mushonga unofanirwa kudzivirirwa kubva kumhepo uye chiedza.
Safety Protection
Chengetedzo yekubata zvakachengeteka
HAPANA moto wakavhurika. Kubata munzvimbo ine mhepo yakanaka. Pfeka zvipfeko zvinodzivirira zvakakodzera. Dzivisa kusangana neganda nemaziso. Dzivisa kuumbwa kweguruva uye aerosols. Shandisa midziyo isiri-sparking. Dzivirira moto unokonzerwa ne electrostatic discharge steam.
