The primary metabolite of ethanol oxidation, is acetaldehyde. This compound is relatively toxic, and it is responsible for alcohol-related flushing, headaches, nausea, and increased heart rate. This enzyme metabolizes acetaldehyde to acetic acid Figure 1. The acetic acid is eventually converted in the cell into carbon dioxide and water. Some people do not have the ability to metabolize acetaldehyde very well. When they drink alcohol, acetaldehyde accumulates in the blood and makes them feel sick.
They have facial flushing, headaches, nausea, vomiting, and a rapid heart rate. The alternative form of ALDH is very inefficient at metabolizing acetaldehyde. People with this genetic mutation do not like to drink alcohol.
Learn more about oxidation. The rate of metabolism remains constant during continued drinking. Why is this important? So, alcohol begins to accumulate in the bloodstream, giving an increased blood alcohol concentration BAC Figure 1. New York: Wiley; Tracey DJ, Baume P. Random House Australia, Alcohol metabolism: an update April Skip to content. It performs more than functions, including: processing nutrients from food; storing energy; making bile to help with digestion of dietary fats; filtering toxic chemicals and bacteria from the body; helping with blood clotting; and processing medicines.
Your liver is also the main place in your body where alcohol is broken down. What happens after I drink alcohol? How quickly you absorb the alcohol depends on several factors, including: the concentration of alcohol in your drink drinks with a higher alcohol concentration are generally absorbed faster ; whether your drink is carbonated champagne, for example, is absorbed more quickly than non-sparkling drinks ; and whether your stomach is full or empty food slows down the absorption of alcohol.
