Different water purity provokes a great variation of the stability of ascorbic acid and isoascorbic acid solutions. The effect of temperature on ascorbate aerobic oxidation was assessed by means of Arrhenius plots from which thermodynamic parameters were derived. The presence of bovine serum albumin drastically reduces the vitamin oxidation rate regardless of stereoisomerism. On the other hand the interaction with alkaline phosphatase, an enzyme inhibited by preincubation with vitamin C, does not modify significantly the stability in the experimental conditions used.
不同的水纯度会引发抗坏血酸和异抗坏血酸溶液稳定性的巨大差异。通过阿伦尼乌斯曲线评估温度对抗坏血酸盐有氧氧化的影响，从中得出热力学参数。无论立体异构情况如何，牛血清白蛋白的存在都会大幅降低维生素的氧化速率。另一方面，与碱性磷酸酶的相互作用（一种通过与维生素C预孵育而被抑制的酶）在所用实验条件下并不会显著改变稳定性。
