Abstract
Potassium formate labeled with C14 was 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.

2. One-Carbon Metabolism**Abbreviations: The recommendations of the IUPAC-IUB Commission are followed in designation of pteroylglutamic acid and its derivatives, e.g., 10-HCOH4PteGlu, N10-formyltetrahydropteroylmonoglutamate, 5,10-CH2 H4 PteGlu, N5, N10-methylenetetrahydropteroylmonoglutamate, and 5-CH3H4PteGlu, N5-methyltetrahydropteroylmonoglutamate [Biochem. J. 102, 19–20 (1967)]. The term “folate” is used to denote metabolically active pteroylglutamates. Other abbreviations are AdoMet—S-adenosylmethionine, SAHC—S-adenosylhomocysteine γ-GCP—γ-glutamylcarboxypepidase, E.C. 3.4.12.10.;Metabolism and Respiration;1980
