Although the pigments in LHCII do not strictly constitute an energy funnel, differences in their transition energies to a certain extent guide the absorbed energy from Cars or Chl b to Chl a until excitations are finally localized primarily on a small number of Chl a molecules constituting t...
Photosynthesis is the ultimate basis of plant productivity and is therefore one of the crucial parameters available for analysis of plant productivity. Photosynthetic energy conversion starts with the absorption of light by the photosynthetic pigments in the two photosystems. The energy of the resulting...
a Electron transmission: Lignin-based solar cells can be made that take advantage of the electron transmission property of lignophenol. Macromolecular lignophenols can equal organic pigments in the generation of electric power and that capability can be further amplified by manipulating their str...
plastid pigmentsRunner bean plants (iPhaseolus coccineus/i L., cv. Pikny Ja) grown hydroponically were treated with Cd (2.5 10sup-5/sup M Cd in the form of 3CdSOsub4/sub 8Hsub2/subO) at different stages of primary leaves development. Ten days after the metal treatment, the changes ...
Pigments, such as loliolide and fucoxanthin, were annotated. Fucoxanthin plays an essential role in harvesting light for photosynthesis and photoprotection82, while loliolide is an apocarotenoid considered as a photo-oxidative or thermal degradation product of carotenoids83. Pheophorbide A, a product of ...

The chemical processes by which cells produce the substances and energy needed to sustain life. In metabolism, organic compounds are broken down to provide heat and energy, while simpler molecules are used to build complex compounds like proteins for growth and repair of tissues. Many metabolic pro...
