BIOGENESIS OF RIBOFLAVIN IN GREEN LEAVES

VI. NON-ENZYMATIC PRODUCTION OF 6-METHYL-7-HYDROXY-8-RIBITYLLUMAZINE FROM NEW ORGANIC REACTION OF 6, 7-DIMETHYL-8-RIBITYLLUMAZINE WITH p-QUINONE

Abstract

1. It was found that V compound could be easily produced through a chemical reaction of G compound and p-quinone under physiological conditions, which might be possible to be extended to the consideration of the biosynthesis of V compound.
2. The chemical reaction was demonstrated to be a dehydrogenetic demethylation reaction by chemical kinetics studies on the reaction.
3. The most plausible mechanism for the chemical reaction was proposed.
