Hi Pepper Mint! Esterification will not occur in the stomach or intestinal tract. While the pH is acidic enough in the stomach, the temps aren't sufficient to overcome Eactivation. The only way to clear alcohol from the blood stream is through enzymatic oxidation. Ethanol is converted to acetaldehyde via ethanol dehydrogenase, and acetaldehyde is converted to acetic acid via acetaldehyde dehydrogenase. The acetic acid can be eliminated through the urinary tract, or taken up in the acetyl Co A cycle. Ascorbic acid is a good free radical trap for any acetaldehyde free radicals, but that's it. Also bear in mind the reaction kinetics are of second order in reactants. Too much acetaldehyde built up in the system slows down the final oxidation step. This is what produces hangovers.
