Carotenoids in photosynthesis.

Wild—type photosynthetic organisms all contain carotenoids. These photosynthetic carotenoids are mainly packaged (together with the chlorophylls or bacteriochlorophylls) into specific pigment-protein complexes. This review lecture summarises the main types of photochemical reactions which carotenoids undergo in vitro and emphasises the organising role of the apoproteins, of these pigment—protei...

On the photophysics and photochemical properties of carotenoids and their role as light-harvesting pigments in photosynthesis

In photosynthetic organisms, carotenoids have been implicated in several diverse roles. Yet, owing to profound technical difficulties encountered in attempting to examine the electronic state energies and dynamics of carotenoids both in vitro and in vivo, several questions remain, and much of the data and interpretations of the results are controversial. This paper will discuss some of these qu...

Quantum coherence and its interplay with protein environments in photosynthetic electronic energy transfer.

Recent experiments suggest that electronic energy transfer in photosynthetic pigment-protein complexes involves long-lived quantum coherence among electronic excitations of pigments. [Engel et al., Nature, 2007, 446, 782-786.] The observation has led to the suggestion that quantum coherence might play a significant role in achieving the remarkable efficiency of photosynthetic light harvesting. ...

Antioxidant effects of carotenoids in a model pigment-protein complex.

The effect of carotenoids on stability of model photosynthetic pigment-protein complexes subjected to chemical oxidation with hydrogen peroxide or potassium ferricyanide was investigated. The oxidation of carotenoid-less and carotenoid-containing complexes was conducted in the presence or absence of ascorbic acid. The progress of the reactions was monitored by use of absorption and fluorescence...

Light Absorption and Energy Transfer in the Antenna Complexes of Photosynthetic Organisms.

The process of photosynthesis is initiated by the capture of sunlight by a network of light-absorbing molecules (chromophores), which are also responsible for the subsequent funneling of the excitation energy to the reaction centers. Through evolution, genetic drift, and speciation, photosynthetic organisms have discovered many solutions for light harvesting. In this review, we describe the und...
