or maybe the article is wrong. when you drink a beer, ethanol is metabolized to acetaldehyde as part of the normal metabolic process, and then on to acetate. You know, the anion of acetic acid, right ? HOAc has two carbons, ya ? Acetaldehyde is easily gone, just wait a while or ingest some cystein. I think the article is full of baloney myself, the very way its worded suggests something to me. Look up ethanol metabolism, identify the enzyme that oxidizes the aldehyde to the carboxylate, and see what other bodily processes that enzyme acts on. Then you all may begin to realize that without it you'd be dead. Those who have been through biochem 101 won't even waste time discussing such nonsensical articles
