ALCOHOL METABOLISM

Alcohol metabolism is the process by which the body breaks down and eliminates alcohol. It primarily occurs in the liver through the action of specific enzymes. The average decrease of blood alcohol level for an adult in one hour is approximately 0.01 percent. This rate, also known as the rate of alcohol metabolism, represents how quickly the liver processes and eliminates alcohol from the bloodstream. Individual variations to this average rate can occur based on the weight, age, sex, genetic factors, food intake, and liver health.
