Abstract

Human placenta contains a single detectable isozyme of alcohol dehydrogenase that has been isolated and characterized. It migrates toward the anode on starch gel electrophoresis and can be stained with pentanol but not ethanol as substrate. Its kinetic and molecular characteristics are identical with those of the recently discovered χ-ADH (Class III) isozyme from human liver. Placental ADH is present in the cytosol of this organ in small amounts, 6mg/kg fresh tissue. It oxidizes ethanol very slowly - even at ethanol concentrations that would reflect intoxication when found in serum. Thus, placental alcohol dehydrogenase cannot play a significant role in the ethanol metabolism of pregnant women. © 1984.
