Alcoholic Liver Disease: Introduction - Johns Hopkins Medicine

WebAlcohol is broken down (i.e., metabolized) in the liver primarily through two pathways: the alcohol dehydrogenase (ADH) pathway and the microsomal ethanol-oxidizing system (MEOS). In people who consume alcohol at moderate levels and/or only occasionally, most of the alcohol is broken down by ADH, an enzyme found in the fluid that fills the cell ... WebThis may be because unlike normal oxidation of ethanol in the mitochondria, MEOS in the endoplasmic reticulum produces NADPH (rather than NADH) which is not available for electron transport and energy production. Potentially, alcohol causes weight loss because the microsomal ethanol oxidising system allows the inefficient use of ethanol to ...
