The main enzymes that break down alcohol are acetaldehyde dehydrogenase and ethanol dehydrogenase.
The scientific name of alcohol is ethanol. After entering the body, ethanol enters the bloodstream through the gastrointestinal mucosa, and the blood is transported to the liver for decomposition. 95% of ethanol is decomposed by the liver, and the enzyme ethanol dehydrogenase is mainly responsible for decomposing ethanol into acetaldehyde to alleviate the discomfort in the stomach.
Acetaldehyde dehydrogenase can break down acetaldehyde into acetic acid, acetaldehyde dehydrogenase exists in the liver, and there are great individual differences, many people drink on the face is due to the lack of acetaldehyde dehydrogenase in the body, resulting in a large number of acetaldehyde can not be broken down and accumulated in the body can not be discharged, causing a series of drunkenness symptoms, such as facial redness, nausea, panic, throbbing headache and other manifestations of a serious threat to the safety of life.
Alcohol is more damaging to the human body, which can damage organs, induce allergies, etc., and should be abstained from as much alcohol as possible.
