A 40-year old manager weighs 150lb. experience abdominal pain post lunch. When questioning him we learned that he consumed 2 12 oz bottle of beer. The alcohol (ethyl alcohol) content of the bottle of beer in a 12 oz is about 5%. Identify the substance produced in the liver that helps catalyze this reaction.
