Physiological role of alcoholsPhysiological role of alcohols
Ethanol in alcoholic beverages has been consumed by humans since prehistoric times. The consumption of large doses of ethanol causes drunkenness (intoxication). Depending upon the dose and the regularity of its consumption, ethanol can cause acute respiratory failure or death. Because ethanol impairs judgment in humans, it can be a catalyst for reckless or irresponsible behavior. The LD50 of ethanol for rats is 10.3 g/kg.
Other alcohols are substantially more poisonous than ethanol, partly because they take much longer to be metabolized and partly because their metabolism produces substances that are even more toxic. Methanol (wood alcohol), for instance, is oxidized to formaldehyde and then to the poisonous formic acid in the liver; accumulation of formic acid can lead to blindness or death.
