摘要：

Under aerobic conditions and in the presence of flavins, light causes the photolysis of mycosporine glutamine into aminocyclohexenone and 2-hydroxy glutaric acid. This photolysis, which is temperature dependent, is also observed when other photosensitizers which are carriers of singlet oxygen replace flavins. This photodestruction also occurs with mycosporine amino alcohols but at reduced rate and probably by another mechanism. © 1990.
