Abstract

The metabolism of 5-[-C] methyltetrahydrofolate in proceeded oxidatively with incorporation of label into purine and thymidylate derivatives. No labelled methionine was formed. ()-5-MethyltetrahydrofoIate, the natural isomer, was not a substrate for the folylpoly--glutamate synthetase although the unnatural ()-isomer was slowly metabolized to the diglutamate form.
