1. Short-term intake of a 2% benzyl alcohol in the rat drinking fluid resulted in sex-dependent inhibition of hepatic alcohol dehydrogenase. 2. Benzyl alcohol intake also inhibited female but not male mitochondrial aldehyde dehydrogenase isoenzymes with the apparent low and high Km. 3. The benzyl alcohol inhibition kinetics were found non-competitive with the major differences in Vmax being confined to the cytoplasmic enzymes. 4. The velocity of the enzymatic reaction was greater for the substrate benzaldehyde than benzyl alcohol. 5. The results suggest sex-dependent hepatic alcohol dehydrogenase-substrate competition between benzyl alcohol and ethanol which may precipitate adverse metabolic interaction particularly in the susceptible female subject. 6. Modulation of the activity of this enzyme by benzyl alcohol may contribute to its toxicity as preservative in parentral injectable solutions.
