Incazelo

I-Vitamin C iyivithamini encibilikayo emanzini, ngamakhemikhali okuthiwa i-L-ascorbic acid, enefomula ye-molecular C ? H ? O ? kanye nesisindo samangqamuzana angu-176.12. Iyisakhi esiyisisekelo esibalulekile emzimbeni womuntu, esinokuncipha okuqinile, esitholakala kabanzi ezitshalweni nasemifino, futhi sibalulekile ekugcineni i-metabolism evamile kanye nempilo yomzimba.

Izakhiwo zomzimba namakhemikhali

Ukuncibilika kwamanzi

Uvithamini C uncibilika kalula emanzini futhi ungamuncwa ngokushesha umzimba womuntu, kodwa ukumunca ngokweqile kungakhishwa ngomchamo.

Izici zokunciphisa kanye ne-antioxidant

Njenge-ejenti yokunciphisa eqinile, ingaqeda ama-radicals mahhala, ivikele amangqamuzana emonakalweni we-oxidative, futhi ikhuthaze ukumuncwa kwensimbi (ukunciphisa i-iron e-trivalent ibe yi-divalent iron).

I-Acidic

Inezici ezine-asidi, izici zamakhemikhali ezisebenzayo, futhi ijwayele ukusabela nezinye izinto (njenge-hydrolysis kanye ne-oxidation).

Ukungazinzi kokushisa

Ngemva kokushisa, kulula ukubola futhi ingasebenzi. Ukupheka isikhathi eside noma ukwelashwa okushisayo kungaholela ekwehleni okukhulu kokuqukethwe kwe-vitamin C ezithelweni nemifino.

Ukufana kukashukela

Isakhiwo samangqamuzana siyafana nesikashukela, sinezici ezithile zokusabela kwe-physicochemical kashukela.

Isifinyezo

Izici ze-physicochemical kavithamini C zinquma umsebenzi wawo webhayoloji nomsebenzi, njengokuncibilika kwamanzi nokuncipha okusekela imiphumela ekhuthaza ukumuncwa kwensimbi, kuyilapho ukuzwela ukushisa kuphakamisa isidingo sokwengezwa ngezithako ezintsha noma izindlela zokupheka eziphusile.
