Where does alcohol dehydrogenase come from?
The answer comes from alcohol dehydrogenase. Alcohol dehydrogenase an enzyme that is found mostly in the liver and stomach. Like its name implies, its job is to start the pathway of alcohol metabolism. Its name also implies the mechanism of action in this process. The prefix 'de' means not, and 'hydro' refers to a hydrogen atom. So, alcohol dehydrogenase works by removing a hydrogen atom from alcohol. The hydrogen atom is bound to part of the enzyme called NAD+ and is later released, regenerating the enzyme for further use.

Methanol is metabolized to formaldehyde by alcohol dehydrogenase. Interestingly methanol poisoning can actually be treated by administering intravenous ethanol to the patient. The ethanol competes with methanol for alcohol dehydrogenase activity, thus slowing down how much methanol alcohol dehydrogenase can convert to formaldehyde.
How does ethanol break down?
When we drink ethanol, alcohol dehydrogenase in the stomach is able to get to work breaking it down. Ethanol that continues through the stomach is absorbed into the blood in the small intestine. Blood in capillaries surrounding the small intestine goes directly to the liver. The main job of the liver is to detoxify the blood, so blood goes directly here from the digestive tract. In the liver there is more alcohol dehydrogenase to break down ethanol in the blood.
What is the job of the liver?

The main indicator of ALDH2 Deficiency is the presence of Alcohol Flush Reaction (known as ‘Asian Flush’ ) when drinking alcohol. Symptoms of Alcohol Flush Reaction may include red facial flushing, raised body temperature, rapid heart rate, inflammation, headache, nausea and dizziness. If you suffer from Alcohol Flush Reaction, there is a very good chance that you have ALDH2 Deficiency.
How Does ALDH2 Deficiency Impact Our Health?
Studies show that people with ALDH2 Deficiency are at higher risk of esophageal cancer, liver cirrhosis and Alzheimer’s. This is due to our weakened ability to break down acetaldehyde in the body. Many people with ALDH2 Deficiency choose not to drink alcohol. This is very helpful because alcohol results in high concentrations of acetaldehyde. But the problem is that acetaldehyde can still enter the body in low levels through other everyday sources such as high sugar foods, coffee, soda, air pollution and cigarette smoke.
What is ALDH2 Deficiency?
ALDH2 stands for Aldehyde Dehydrogenase 2 and is an important enzyme responsible for the breakdown of toxins, primarily acetaldehyde.
