Detoxification is the physiological or medicinal removal of toxic substances from a living organism, including the human body, which is mainly carried out by the liver. Additionally, it can refer to the period of withdrawal during which an organism returns to homeostasis after long-term use of an addictive substance. (Source: https://en.wikipedia.org/wiki/Detoxification)
Ethanol is metabolised in liver with ADH, which oxidises ethanol to acetaldehyde. The latter is a toxic substance and can cause tissue damage, therfore, it must be further oxidised by ALDH to form a non-toxic product, acetate.
Ethanol can be an addictive substance.
Why is ethanol metabolism catagorized as catabolism? Could it also be detoxification (according to the assumptions above)? Why not?
Is ethanol metabolism a catabolic metabolic pathway because it provides NADH and acetate (which can be activated to acetyl-CoA) for anabolic reactions? Or is there another reason?
