Reset Help 1. When you drink an alcoholic beverage, metabolism of the food starts in the stomach, where the enzyme alcohol dehydrogenase and other enzymes break down some of the alcohol into acetaldehyde, then to acetate, and eventually into carbon dioxide and water. Since some of the alcohol is absorbed in the esophagusstomach there will slow the absorption of alcohol into the bloodstream. Most of the alcohol is absorbed in the small intestine and carried to theliver where most of the alcohol is metabolized. However, the liver can only metabolize one standard drink per hour. The additional alcohol, not metabolized by the liver, enters the bloodstream and travels throughout the body. It can be excreted in the urine, sweat, and breath . As unmetabolized alcohol reaches the brain, the individual will become intoxicated large intestine ethanol methanol Submit Previous Answers Request AnswerExplanation / Answer
Alcohol metabolism:
The metabolism of alcohol is the process in which the body converts alcohol into a less toxic substance.
Alcohol metabolism follows three steps:
Consumption – getting the liquid into your body
Absorption – absorbing the alcohol into your bloodstream
Processing – converting the I) alcohol into
II) acetaldehyde , then III) acetate (or acetic acid) and finally into fatty acids, carbon dioxide, and water.
20% of consumed alcohol is immediately absorbed into the bloodstream before reaching the rest of the gastrointestinal tract.
Furthermore alcohol is an irritant to the sensitive lining of the esophagus and the excess consumption can significantly raise your risk of esophageal cancer.
Alcohol is absorbed into the blood through the stomach walls.
Moreover the part of alcohol which is not absorbed by the stomach is absorbed in the small intestine.
Alcohol is processed by the liver as it arrives from the bloodstream.
The liver produces enzymes called alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH).
Alcohol metabolism via ADH produces a secondary product more toxic than alcohol itself – acetaldehyde
Acetaldehyde is then converted into acetate by ALDH
Acetate is digested into fatty acids, CO2 & water.
The consumption of methanol may cause optical neuropathy.
Alcohol may cross blood brain barrier (BBB) also hence cause Impaired Judgment and other related effects.
