The effectiveness of carotenoids as antioxidants is dependent on a number of influencing factors. It is likely that carotenoids exhibit a tendency to lose their effectiveness as antioxidants or act as prooxidants. In this paper, factors influencing the antioxidant or prooxidant activities of carotenoids such as the molecule structure of carotenoids, the location or site of action of the carotenoid molecule within the cell, the concentration of carotenoids, the properties of reactants, the partial pressure of oxygen and the interaction with other antioxidants were reviewed.
类胡萝卜素作为抗氧化剂的有效性取决于许多影响因素。类胡萝卜素可能会表现出作为抗氧化剂失去其有效性或充当促氧化剂的倾向。本文综述了影响类胡萝卜素抗氧化或促氧化活性的因素，如类胡萝卜素的分子结构、类胡萝卜素分子在细胞内的作用位置或位点、类胡萝卜素的浓度、反应物的性质、氧分压以及与其他抗氧化剂的相互作用。
