    Biochemical Aspects of the Hepatic Microsomal Ethanol-oxidizing System (MEOS): Resolved Initial Controversies and Updated Molecular Views
    Author(s): Rolf Teschke*

    The hepatic microsomal ethanol-oxidizing system (MEOS) was initially confronted with much uncertainty, skepticism, scientific antagonism, and heavy discussions. Viewed as scientific challenges, this stimulated further research, and led to its successful separation from both, alcohol dehydrogenase and catalase, and its reconstitution that allowed defining the individual components of MEOS: cytochrome P450 (CYP), reductase, and phospholipids. Subsequently, it was challenging to elucidate the molecular basis of the microsomal ethanol oxidation. Unlike a usual dehydrogenation or simple oxidation process, ethanol oxidation via MEOS proceeds via reactive intermediates, commonly known as reactive oxygen species (ROS) and generated by various microsomal CYP isoenzymes including CYP 2E1, all of which are established components of MEOS. Due to its radical scavenging properties, ethanol combines.. Read More»
