What are the metabolites of Alcohol?

In the metabolism of alcohol is the oxidation of ethanol to acetaldehyde. Although the liver converts acetaldehyde into acetic acid, it reaches a saturation point where some of it escapes into the blood stream. Acetaldehyde in the brain may inhibit enzymes designed to convert certain nerve transmitters from aldehydes to acids. The nerve transmitters that aculate may then react with the acetaldehyde to form compounds which are startlingly similar to certain morphine-type compounds.
