Effects of ascorbic acid and 5,6-O-isopropylidene-2,3-O-dimethylascorbic acid on final product formation in radiolysis of ethanol, aqueous solutions of ethanol, ethylene glycol, alpha-methylglycoside, maltose, alpha-glycerophosphate, and alpha-glucose phosphate were studied. It was found that ascorbic acid is able to suppress reactions involving various alpha-hydroxyl-containing carbon-centered radicals and depending on the experimental conditions can either oxidize or reduce alpha-hydroxyethyl radicals.
研究了抗坏血酸和5,6-O-异亚丙基-2,3-O-二甲基抗坏血酸对乙醇、乙醇水溶液、乙二醇、α-甲基糖苷、麦芽糖、α-甘油磷酸酯和α-葡萄糖磷酸酯辐射分解中最终产物形成的影响。发现抗坏血酸能够抑制涉及各种含α-羟基的碳中心自由基的反应，并根据实验条件，它可以氧化或还原α-羟乙基自由基。
