WebPheophytin or Pheo is a chlorophyll molecule lacking a central Mg 2+ ion which serves as the first electron carrier intermediate in the electron transfer pathway of photosystem II in plants and the photosynthetic reaction center RC P870 found in purple bacteria. WebWhat is Pheophytin A and B? occurring a and b derivatives of chlorophyll, such as pheophytin, chlorophyllide, and pheophorbide, are present in plants as breakdown products [3], and in animals as the products of chlorophyll digestion [4]. The simplest derivative, pheophytin (Figure 1), has had the Mg atom dechelated from its porphyrin ring.
