Study Notes
Ethanol Metabolism
- Ethanol (beverage alcohol) is absorbed from the small intestine and affects nerve cell membranes.
- The liver converts approximately 90% of ethanol into acetaldehyde and then acetic acid.
- About 10% of ethanol is eliminated through sweat and urine.
- Peak blood alcohol concentration (BAC) is reached approximately 90 minutes after ingestion.
- One standard drink (1.5 oz. alcohol) raises BAC by approximately 0.02% in an average person.
- The average rate of alcohol clearance is about one standard drink per hour.
- A blood alcohol content (BAC) of 0.08% is the legal limit in the U.S.
- Consuming four standard drinks results in a BAC exceeding the legal limit approximately 1.5 hours after consumption.
