Bacteriopheophytin

Bacteriopheophytin, a photosynthetic pigment found in bacteria, is a demetallated form of bacterial chlorophyll where the magnesium ion at the center is replaced by two hydrogen atoms. It functions as an electron acceptor within the reaction center (RC) of purple bacteria, playing a crucial role in the electron transfer process [1].
