Carotenoids are pigments which play a major role in the protection of plants against photooxidative processes. They are efficient antioxidants scavenging singlet molecular oxygen and peroxyl radicals. In the human organism, carotenoids are part of the antioxidant defense system. They interact synergistically with other antioxidants; mixtures of carotenoids are more effective than single compounds. According to their structure most carotenoids exhibit absorption maxima at around 450 nm. Filtering of blue light has been proposed as a mechanism protecting the macula lutea against photooxidative damage. There is increasing evidence from human studies that carotenoids protect the skin against photooxidative damage.

类胡萝卜素的抗氧化活性。

类胡萝卜素是在保护植物免受光氧化过程中起主要作用的颜料。它们是清除单线态分子氧和过氧自由基的有效抗氧化剂。在人体中,类胡萝卜素是抗氧化防御系统的一部分。它们与其他抗氧化剂协同作用。类胡萝卜素的混合物比单一化合物更有效。根据它们的结构,大多数类胡萝卜素在约450 nm处表现出最大吸收。提出了将蓝光过滤作为保护黄斑免受光氧化损伤的机制。人体研究显示,越来越多的证据表明类胡萝卜素可以保护皮肤免受光氧化损伤。
