Tsanangudzo

Vitamin C ivhitamini inonyungudika mumvura, kemikari inonzi L-ascorbic acid, ine molecular formula yeC ? H ? O ? uye molecular uremu hwe176.12. Icho chinhu chakakosha chekudya chemuviri wemunhu, chine kudzikisira kwakasimba, chiripo zvakanyanya mumichero mitsva nemiriwo, uye yakakosha kuchengetedza yakajairika metabolism uye hutano hwemuviri.

Zvenyama uye zvemakemikari zvinhu

Kunyungudika kwemvura

Vhitamini C inonyungudika zviri nyore mumvura uye inogona kukurumidza kubatwa nemuviri wemunhu, asi kudyiwa kwakanyanya kunogona kuburitswa nemuweti.

Reductive uye antioxidant zvinhu

Seyakasimba yekudzikisa mumiriri, inogona kubvisa mahara radicals, kudzivirira maseru kubva mukukuvadzwa kweoxidative, uye kukurudzira kunyudzwa kwesimbi (kuderedza trivalent iron kune divalent iron).

Acidic

Iine acidic hunhu, inoshanda kemikari zvimiro, uye inokwanisa kuita nezvimwe zvinhu (senge hydrolysis uye oxidation).

Kusagadzikana kwekupisa

Mushure mekupisa, zviri nyore kuora uye kusashanda. Kubika kwenguva refu kana kurapwa kwakanyanya kunogona kukonzera kuderera kukuru kwevhitamini C mumichero nemiriwo.

Shuga kufanana

Chimiro chemolecular chakafanana neicho cheshuga, chine mamwe maitiro e physicochemical maitiro eshuga.

Summary

Iyo physicochemical zvimiro zvevhitamini C inotarisisa kuita kwayo zvipenyu uye basa, sekunyungudika kwemvura uye kudzikisira inotsigira iyo antioxidant uye iron absorption inosimudzira mhedzisiro, nepo kupisa senitivity kunoratidza kudiwa kwekuwedzera kuburikidza nezvinonhuhwirira zvitsva kana nzira dzekubika dzine musoro.
