Alcohol is metabolized quickly and a high percentage of the amount consumed is actually metabolized. In fact, over 90% of alcohol is metabolized in the liver, while 2-5% is excreted without any change from the body through sweat, urine, and breath. The scientific explanation is that your body metabolizes alcohol by oxidizing the ethanol to acetaldehyde (using alcohol dehydrogenase) to acetic acid to carbon dioxide and water. The final alcohol metabolites are not harmful, nor is the alcohol itself, however, the intermediate metabolite, acetaldehyde is the culprit in causing hangover effects.
