muaj nuj nqi | Vitamin C zoo sib xws hauv kev teeb tsa rau cov piam thaj. Nws yog ib qho tshuaj sib txuas polyhydroxy. Ob ob leeg nyob ib sab enol-hom hydroxyl pawg hauv qhov thib 2 thiab 3 txoj haujlwm ntawm cov lwg me tau yooj yim cais tawm H +, yog li lawv muaj cov kua qaub. ascorbic acid. Vitamin C muaj zog reducibility thiab yooj yim oxidized rau dehydrogenated vitamin C, tab sis nws cov tshuaj tiv thaiv yog thim rov qab, thiab ascorbic acid thiab dehydroascorbic acid muaj tib lub zog ua haujlwm, tab sis dehydroascorbic acid tseem oxidize tsim diketone Leuconic acid, qhov tshuaj tiv thaiv yog irreversible thiab kiag li plam qhov kev ua haujlwm ntawm lub cev. |
