Results and discussion

Any other information on results incl. tables

The carboxylate and the methyl groups correspond to the alcoholic function and to its adjacent methylene group, repsectively, of the 2 -hydroxyethyl unit of triethylamine. A 1,2 shift of a hydrogen (deuterium) atom from -CH2 -O- to =N-CH2- without exchange with the medium was observed. This fact gives evidence that a radical mechanism occurs involving the enzyme and/or conenzyme molecule as a hydrogen carrier.
