摘要:
Potassium formate labeled with C14was fed to sprouting barley, and choline and hordenine (N-dimethyltyramine) were isolated from the roots. Both of these substances bore the labeled carbon largely, if not entirely, in the methyl groups, as shown by means of degradation experiments. This indicates that the N-methyl groups of these compounds originate from formate ions.
