title: Methanol metabolism in acatalasemic mice.
abstract: The methanol metabolism in acatalasemic mice was studied by administering [14C]methanol and [14C]formic acid to acatalasemic and normal mice and determining the radioactivity of exhaled carbon dioxide. Methanol metabolism was also studied in acatalasemic and normal mice treated with 3-amino-1,2,4-triazole (AT), which is known to be an inhibitor of catalase (EC 1.11.1.6). The metabolism of methanol and formic acid was inhibited in acatalasemic mice as seen by reduced [14C]CO2 production. Similar results were obtained when AT was given prior to the methanol injection into the normal and acatalasemic mice. The results indicate the peroxidative activity of catalase plays the major role in the methanol metabolism in mice. On the other hand similar studies with [1-14C] ethanol showed that the metabolism of ethanol was not inhibited in acatalasemic mice.
