Carotenoids in photosynthesis: absorption, transfer and dissipation of light energy
نویسنده
چکیده
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°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.

Singlet energy dissipation in the photosystem II light-harvesting complex does not involve energy transfer to carotenoids.
The energy dissipation mechanism in oligomers of the major light-harvesting complex II (LHC II) from Arabidopsis thaliana mutants npq1 and npq2, zeaxanthin-deficient and zeaxanthin-enriched, respectively, has been studied by femtosecond transient absorption. The kinetics obtained at different excitation intensities are compared and the implications of singlet-singlet annihilation are discussed....

Carotenoids are organic pigments commonly synthesized by plants, algae and some micro-organisms. Through absorption of light energy, carotenoids facilitate photosynthesis and provide protection against photo-oxidation. While it was presumed that all carotenoids in animals were sequestered from their diets, aphids were recently shown to harbour genomic copies of functional carotenoid biosynthesi...
متن کاملThermal Dissipation Related to Chlorophyll Fluorescence and Photosynthesis*
Energy taken up by light absorption of the leaf pigments is transformed in the process of the photosynthetic quantum conversion into photosynthesis, chlorophyll fluorescence and thermal dissipation. The mostly inverse correlation between chlorophyll fluorescence and photosynthetic activity has been extensively studied in the past, whereas only few studies dealt with the thermal dissipation. In ...

Carbonyl carotenoids are important constituents of the antenna complexes of marine organisms. These carotenoids possess an excited state with a charge-transfer character (intramolecular charge transfer state, ICT), but many details of the carotenoid to chlorophyll energy transfer mechanisms are as yet poorly understood. Here, we employ femtosecond transient absorption spectroscopy to study ener...
متن کاملConcentration Effect on Quenching of Chlorophyll a Fluorescence by All-Trans-β-Carotene in Photosynthesis.
Absorption, fluorescence spectra of chlorophyll a (Chl-a) and all-trans-β-carotene (β-Car) mixing solution are investigated in different polarity and polarizability solvents. The carotenoids regulate the energy flow in photosynthesis by interaction with chlorophyll, leading to an observable reduction of Chl-a fluorescence. The fluorescence red shifts with the increasing solvent polarizability. ...
