A protocol for determining the location of antioxidants (AOs) in a micro-heterogeneous medium was applied to three series of AOs with increasing hydrophobicities: chromancarboxylic acid (“Trolox”) esters, caffeic acid and its esters, and gallic acid and its esters. The observed paradoxical behaviour of these and other commonly encountered antioxidants was rationalized with the aid of a pictorial simile, the “diving-swan” analogy, that explains the orientation and location of an amphiphobic AO when it reacts with a radical probe in the micellar interface.

两性抗氧化剂在胶束系统中的位置:潜水天鹅类比

确定微异质性介质中抗氧化剂(AOs)位置的方案已应用于疏水性增加的三个系列AO:苯并二羧酸(“ Trolox”)酯,咖啡酸及其酯,没食子酸及其酯。借助绘画般的比喻“ diving-swan”比喻,合理地观察到了这些和其他常见抗氧化剂的自相矛盾行为,该比喻解释了两亲性AO与胶束界面中的自由基探针反应时的方向和位置。 。
