I-CAS egqunywe yiVitamin C: 50-81-7 Umthengisi woMvelisi

IVithamini C ithathwa njenge-enzyme cofactor okanye i-antioxidant yakudala kodwa ikwathathwa njengesixhobo sokutshintsha kwi-metal ion reaction. Kwaye yonke le misebenzi yeVithamini C inxulumene nepropathi ye-antioxidation. I-L-ascorbic acid ikakhulu ibonisa iipropathi ze-antioxidant. Ikhusela izityalo kwi-oxidative stress kunye nezilwanyana ezincancisayo kwizifo ezinxulumene ne-oxidative stress. I-L-ascorbic acid ikakhulu ikhusela kwi-hydroxyl radicals, i-superoxide kunye ne-singlet oxygen. Ukongeza, ikwanciphisa i-membrane-linked antioxidant α-tocopherol (uhlobo lwe-oxidised). I-L-Ascorbic acid yonyusa i-endothelium-dependent vasodilation kwizifo ezahlukeneyo, kubandakanya isifo seswekile, isifo se-coronary artery, uxinzelelo lwegazi oluphezulu kunye nokusilela kwentliziyo okungapheliyo.
