Ingcaciso

I-Vitamin C i-vitamin e-soluble yamanzi, i-chemically ebizwa ngokuba yi-L-ascorbic acid, ene-molecular formula ye-C ? H ? O ? kunye ne-molecular weight ye-176.12. Sisakhamzimba esisisiseko esibalulekileyo kumzimba womntu, esinokuncitshiswa okuqinileyo, sifumaneka ngokubanzi kwiziqhamo kunye nemifuno, kwaye ibalulekile ekugcineni imetabolism eqhelekileyo kunye nempilo yomzimba.

Iimpawu zomzimba kunye neekhemikhali

Ukunyibilika kwamanzi

IVithamin C inyibilika ngokulula emanzini kwaye inokufunxwa ngokukhawuleza ngumzimba womntu, kodwa ukutya okugqithisileyo kunokukhutshwa ngomchamo.

Iipropati zokunciphisa kunye ne-antioxidant

Njenge-ejenti yokunciphisa eyomeleleyo, inokuphelisa i-radicals yamahhala, ikhusele iiseli emonakalweni we-oxidative, kwaye ikhuthaze ukuxutywa kwentsimbi (ukunciphisa i-iron trivalent kwi-iron divalent).

I-Acidic

Uneempawu ze-acidic, iipropati zekhemikhali ezisebenzayo, kwaye zivame ukusabela kunye nezinye izinto (ezifana ne-hydrolysis kunye ne-oxidation).

Ukungazinzi kweThermal

Emva kokufudumeza, kulula ukubola kwaye ingasebenzi. Ukupheka kwexesha elide okanye unyango oluphezulu lobushushu kunokukhokelela ekunciphiseni okukhulu kwe-vitamin C kwiziqhamo kunye nemifuno.

Ukufana kweswekile

Ulwakhiwo lwemolekyuli luyafana nolweswekile, luneempawu zokusabela kwi-physicochemical yeswekile.

Isishwankathelo

Iimpawu ze-physicochemical ze-vitamin C zigqiba umsebenzi wayo webhayoloji kunye nomsebenzi, njengokunyibilika kwamanzi kunye nokunciphisa ukuxhasa i-antioxidant kunye ne-iron absorption ekhuthaza iziphumo, ngelixa ubushushu bobushushu bubonisa isidingo sokuxhaswa ngokusebenzisa izithako ezintsha okanye iindlela zokupheka ezifanelekileyo.
