I-CAS Embozwe yiVithamini C: 50-81-7 Umhlinzeki Womkhiqizi

I-Vitamin C ibhekwa njenge-cofactor noma i-antioxidant yakudala kodwa futhi njengento yokuguquka ekusabeleni kwe-ion yensimbi. Futhi yonke le misebenzi ye-vitamin C ihlobene nempahla ye-antioxidation. I-L-ascorbic acid ikhombisa kakhulu izakhiwo ze-antioxidant. Ivikela izitshalo ekucindezelekeni kwe-oxidative kanye nezilwane ezincelisayo ezifweni ezihambisana nokucindezeleka kwe-oxidative. I-L-ascorbic acid ivikela kakhulu kuma-radicals e-hydroxyl, i-superoxide kanye ne-singlet oxygen. Ngaphezu kwalokho, iphinde yehlise i-α-tocopherol exhunywe ku-membrane (ifomu le-oxidised). I-L-Ascorbic acid ithuthukisa i-vasodilation encike ku-endothelium ezifweni ezahlukahlukene, kufaka phakathi isifo sikashukela, isifo semithambo yenhliziyo, umfutho wegazi ophakeme kanye nokwehluleka kwenhliziyo okungapheli.
