Alcohol Dehydrogenase is an enzyme found primarily in the liver that plays a crucial role in metabolizing alcohol. It converts ethanol, the active ingredient in alcoholic beverages, into acetaldehyde, a toxic compound. This process is essential for the body to eliminate alcohol and reduce its effects. The activity of Alcohol Dehydrogenase can vary among individuals due to genetic differences, which can influence how quickly alcohol is processed. Some people may experience stronger effects from alcohol due to lower enzyme activity, while others may metabolize it more efficiently, leading to reduced intoxication levels.
