Pheophytin polarity
Web1). Pheophytin a2 was less polar and eluted later (8 1.0 min). Both peaks have similar acid ratios, Chromatographic behavior (Ta- ble 2), and absorbance at 4 10 and 666 nm. Similar … Pheophytin is the first electron carrier intermediate in the photoreaction center (RC P870) of purple bacteria. Its involvement in this system can be broken down into 5 basic steps. The first step is excitation of the bacteriochlorophylls (Chl)2 or the special pair of chlorophylls. This can be seen in the following … See more Pheophytin or phaeophytin is a chemical compound that serves as the first electron carrier intermediate in the electron transfer pathway of Photosystem II (PS II) in plants, and the type II photosynthetic reaction center (RC … See more In biochemical terms, pheophytin is a chlorophyll molecule lacking a central Mg ion. It can be produced from chlorophyll by treatment with a weak acid, producing a dark bluish waxy pigment. The probable etymology comes from this description, with pheo meaning … See more • Photosynthesis • Photosystem • Chlorophyll • Reaction center • P680 • Biosynthesis of chlorophyllide a (precursor to pheophytin) See more In 1977, scientists Klevanik, Klimov, Shuvalov performed a series of experiments to demonstrate that it is pheophytin and not See more In photosystem II, pheophytin plays a very similar role.
