Characterization of fucoxanthin triplet-state in pyridine and photoprotection in the LHC of Aureococcus anophagefferens
Abstrakt
Spectroscopic properties of the triplet state of the carotenoid fucoxanthin were studied in pyridine, thylakoid membranes and isolated light-harvesting complex of the alga Aureococcus anophagefferens. Extinction coefficient of fucoxanthin triplet absorption, and rate constant of triplet transfer from chlorophyll a to fucoxanthin in solution were estimated.
