If all of the chlorophylls are identically arranged in a chlorosome, then the energy from the photon, once it is absorbed, is going to wander around over all of those chlorophylls, which could take a long time. ❋ Unknown (2009)
“Indeed, the reason that chlorophylls became more complex was to increase light-harvesting efficiency,” said Bryant. ❋ Unknown (2009)
The scientists found that the chlorophylls are highly efficient at harvesting light energy. ❋ Unknown (2009)
The bacteria contain structures called chlorosomes, which contain up to 250,000 chlorophylls. ❋ Unknown (2009)
But compared to the green chlorophylls and multihued anthocyanins, the carotenoids are the model of steadfastness. ❋ Harold McGee (2004)
Their primary photosynthetic pigments are chlorophylls, with smaller amounts of carotenoids, and they store energy in the form of starch. ❋ Harold McGee (2004)
Green Chlorophylls The earth is painted green with chlorophylls, the molecules that harvest solar energy and funnel it into the photosynthetic system that converts it into sugar molecules. ❋ Harold McGee (2004)
Ironically, prolonged exposure to intense light also damages chlorophylls. ❋ Harold McGee (2004)
Their other home is the photosynthetic membranes of chloroplasts, where there is one carotenoid molecule for every five or so chlorophylls. ❋ Harold McGee (2004)
The structure shows the precise arrangement in the L and M subunits of the photochemically active groups – two chlorophyll molecules forming a dimer, two monomeric chlorophylls, two pheophytin molecules (these lack the central magnesium ion of chlorophyll), one quinone molecule, called ❋ Unknown (1988)
It is a mixture of two somewhat different but yet closely related chlorophylls, one of them being blue-green, the other yellowgreen, and the former occurring more richly in the leaves than the latter. ❋ Unknown (1966)
In doing so he has been able to carry out a thorough investigation of the large amount of the various derivatives which can be produced from these two different chlorophylls, and as a result of this means he has brought a desirable clarity and lucidity into a field of chlorophyll chemistry, which was previously very complicated and confused. ❋ Unknown (1966)
By means of the results obtained regarding both these yellow pigments and the chlorophylls he has paved the way for new biological researches into the part played by the different leaf pigments in the assimilation of carbonic acid. ❋ Unknown (1966)
Fat of meat: fat of milk; oil of corn, wheat, etc. The ingredients of the "ether extract" of animal and vegetable foods and feeding stuffs, which it is customary to group together roughly as fats, include, with the true fats, various other substances, as lecithians, and chlorophylls. ❋ Adelaide Hoodless (1884)
"In any case, we need to reconsider the previous assumption that chlorophylls in ageing leaves are always disposed of by a general route leading to nonfluorescent decomposition products," says Kräutler. ❋ Unknown (2010)
