摘要：

The functioning of carotenoids in photosynthesis is discussed in relation to the reaction mechanism. The energy transfer process from the allenic carotenoid, fucoxanthin, to chl a was intensively investigated in the newly isolated fucoxanthin-chl a/c protein assembly (FCPA) from a brown alga Dictyota dichotoma. The transfer time was shorter than 3 ps at 15-degrees-C. The energy level responsible for transfer may not be the Qx band of chl a, contrary to the proposal for the transfer in the bacterial antenna system.
