Carotenoids play diverse roles in biology and medicine. Both the quenching of singlet oxygen (energy transfer) and interaction with oxy-radicals (electron transfer, H-atom transfer and addition reactions) are key processes in understanding many of these roles. Much previous work in 'simple' solvents is reviewed and new results in cell membrane models are presented. The possible consequences of using carotenoids as dietary supplements are discussed.
类胡萝卜素在生物学和医学中发挥着多种作用。单线态氧猝灭(能量转移)以及与氧自由基的相互作用(电子转移、氢原子转移和加成反应)都是理解这些作用的关键过程。本文回顾了此前在“简单”溶剂中的大量工作,并展示了细胞膜模型中的新结果。还讨论了将类胡萝卜素用作膳食补充剂可能产生的后果。
