[4] [6] Alcohol dehydrogenase and aldehyde dehydrogenase are present at their highest concentrations (in liver mitochondria). [98] [107] But these enzymes are widely expressed throughout the body, such as in the stomach and small intestine. [2] Some alcohol undergoes a first pass of metabolism in these areas, before it ever enters the ...
“When alcohol is metabolized, it produces acetaldehyde, a toxic compound that damages DNA and impairs the body’s ability to repair this damage,” says Andrews. “This DNA damage can set the ...
Here's how alcohol affects a person's body, from a first sip to potential long-term fallout. ... it's going to take about six to seven hours for the football-sized liver to metabolize that alcohol ...

Alcohol flush reaction is a condition in which an individual's face or body experiences flushes (appears red) or blotches as a result of an accumulation of acetaldehyde, a metabolic byproduct of the catabolic metabolism of alcohol.

Following the U.S. surgeon general’s new advisory warning of alcohol’s link to multiple cancers, a Florida neurosurgeon and longevity doctor shares his thoughts on why people should stop drinking.
Direct alcohol tolerance is largely dependent on body size. Large-bodied people will require more alcohol to reach insobriety than lightly built people. [4] The alcohol tolerance is also connected with activity of alcohol dehydrogenases (a group of enzymes responsible for the breakdown of alcohol) in the liver, and in the bloodstream.
