I-AScorbic Acid
Intshayelelo
I-Vitamin C, ekwaziwa ngokuba yi-L-ascorbic acid, sisondlo esibalulekileyo kwizilwanyana ezinde kunye nezinye izinto ezimbalwa eziphilayo. I-Ascorbic acid inokuveliswa yi-metabolism kwizinto ezininzi eziphilayo, kodwa abantu ngabona bahlukileyo ngokucacileyo. Eyona nto yaziwayo kukuba ukungabikho kwe-vitamin C kwiChemicalbook kunokubangela i-scurvy. Iqela le-pharmacokidic le-vitamin C yi-ascorbic acid ion. Emzimbeni, i-vitamin C yi-antioxidant kuba inokukhusela umzimba kwingozi yee-oxidising agents, kwaye i-vitamin C nayo yi-coenzyme.
Iipropati ze-physicochemical
IVithamini C inyibilika lula emanzini, inyibilika kancinci kwi-ethanol, ayinyibiliki kwi-ether, i-chloroform, i-benzene, i-petroleum ether, ioyile, amafutha. Isisombululo samanzi sibonisa ukusabela kwe-asidi. Inganyibilika ngokukhawuleza ibe yi-dehydroascortic acid emoyeni, inevumba elimuncu elifana ne-citric acid. Yinto enamandla yokunciphisa, kwaye emva kokugcinwa ixesha elide, ijika kancinci ibe ngamanqanaba ahlukeneyo omthubi we-chemical book. Le mveliso ifumaneka kuzo zonke iintlobo zemifuno neziqhamo ezintsha. Le mveliso idlala indima ebalulekileyo kwi-oxidation yebhayoloji kunye nokunciphisa kunye nokuphefumla kweeseli, okunceda ukwenziwa kwe-nucleic acid kwaye ikhuthaza ukuveliswa kweeseli ezibomvu zegazi. Inganciphisa neFe3+ ibe yiFe2+, ukuze kube lula ukufunxwa ngumzimba womntu kwaye ibe luncedo kwimveliso yeeseli.
SEBENZISA
IVithamin C ithatha inxaxheba ekuvelisweni kwe-collagen emzimbeni. Inefuthe lokuthomalalisa iityhefu kwaye ikhuthaze ukuveliswa kwee-antibodies, ezinokuphucula umsebenzi wokukhupha ubuthi emzimbeni. Kwizonyango, isetyenziselwa kakhulu ukuthintela okanye ukunyanga i-scurvity, kunye nokubola kwamazinyo, ithumba leentsini, i-anemia, ukukhula kunye nophuhliso ukungami kunye nezinye izifo ezibangelwa kukungabikho ngokwaneleyo kwe-ascorbic acid kwiChemicalbook. Ekulungisweni kokutya, isetyenziswa njengesithambisi seevithamini kwijusi yeorenji egxininisiweyo, iikristale zejusi, iilekese, ijeli yeziqhamo, ijam yeziqhamo, njl.
