The stability of pigments in the thalli and extracts of the Barents Sea fucus algae

open access: yesVestnik MGTU, 2019
Fucus algae of the Barents Sea are a promising source of biologically active substances (BAS), including carotenoid and chlorophyll pigments. The main direction of processing these types of brown algae is aimed at obtaining polysaccharides, and therefore

A New Chlorophyll Degradation Pathway [PDF]

open access: yesThe Plant Cell, 2009
Chlorophyll degradation is vital during leaf senescence and fruit ripening, as it allows for recycling of nitrogen and other nutrients and for protection from buildup of phototoxic chlorophyll intermediates ([Hortensteiner, 2006][1]).

Two-Dimensional Electronic Spectroscopy of Chlorophyll a: Solvent Dependent Spectral Evolution [PDF]

open access: yes, 2015
The interaction of the monomeric chlorophyll Q-band electronic transition with solvents of differing physical-chemical properties is investigated through two-dimensional electronic spectroscopy (2DES). Chlorophyll constitutes the key chromophore molecule

Covalently linked chlorophyll a dimer: A biomimetic model of special pair chlorophyll [PDF]

open access: yesProceedings of the National Academy of Sciences, 1976
The synthesis of a covalent dimer of chlorophyll a which possesses properties strikingly similar to those exhibited by P700 special pair chlorophyll in vivo is described. The covalent dimer is characterized by several spectroscopic techniques.
