These high-chlorophyll a waters have lower temperatures than those of surrounding waters, indicating vertical mixing of nutrient-rich subsurface water that is attributable to the topographical features of the Sulu Ridge. Differences in photosynthetic parameters, primary productivity and the phytoplankton ...
other known chlorophylls, has been extracted from photosystem I (PSI) sub-chloroplast particles of the green alga Scenedesmus obliquus; it was suggested that this chlorophyll is either the chromophore ofP–700 or the chromophore of another holochrome associated in a 1:1 molar ratio withP–700....
The role of vanadium in green plants. III. Influence on cell division of Chlorella Vanadium, although essential for growth and chlorophyll formation in unicellular green algae, reveals toxic influences on cell division of Chlorella pyrenoidosa, these disturbances arising in the same range of V-concent...
In this connexion, it is of interest to note that no instance has ever been reported of the occurrence of the green photosynthetic biochrome, chlorophyll, in the absence of carotenoids, whereas the reverse condition is very common, in that countless bacteria and fungi synthesize one or more ...

For example, magnesium and calcium atoms, which are part of the structure of the chlorophyll in leaves, also participate in photosynthesis. They also play significant roles in enzyme catalysis and muscle contraction. The utilization of barium ions as a part of the compound structures of superconduct...
and an emeritus professor of the University of Cambridge. He was the first to determine the full structure of chlorophyll (in 1967) and was involved in the development of the synthesis of vitamin B12 by Robert Burns Woodward. He has made major contributions to the use of organosilicon compounds...

structure of organic compounds did not exist, indicated only the possibility, in principle, of synthesizing such compounds as fats (P. E. M. Berthelot) and carbohydrates (A. M. Butlerov). Indigo, camphor, and other relatively simple compounds were subsequently synthesized in accordance with a ...
