Due to the unique structure of chlorophyll molecules, these act as oxidation-reduction catalysis in both chemical and photosensitized reactions. Some amount of chlorophyll is also added to sun protection creams due to its ability to provide protection against polychromatic radiation. A derived form of ...

and water taken up by plant roots; the balance is oxygen, released back to the atmosphere. Almost half a century passed before theconceptof chemical energy had developed sufficiently to permit the discovery (in 1845) that light energy from the sun is stored as chemical energy in products forme...
During heat killing process, high temperature could change the chemical structure of chlorophyll, the central Mg atom of the porphyrin ring could be removed and chlorophyll was converted into phaeophytin (Fig. 2b). Previous study also reported the formation of phaeophytin during chlorophyll ...

S. Tsvet (Tswett) was the first to distinguish chlorophylls a and b, using the chromatographic method, which he developed. The chemical structure of chlorophyll was elucidated by the German scientists R. Willstátter, A. Stoll (1913), and H. Fischer (1930–40). The complete synthesis of ...

The resulting Chlcatabolite in the plant extract was subjected to chemical degradation by chromic acid. 3-(2-Hydroxyethyl)-4-methyl-maleimide, the key fragment that originates from the Chl catabolite, was isolated. High resolution H-, H-NMR and mass spectroscopy unequivocally demonstrates that a ...
