The fluorescence-pH curve of the new flavin, flavin cyclic 2', 5'-mononucleotide, was so significantly different from those of riboflavin and FMN that the percent fluorescences of the new flavin toward riboflavin or FMN were 95% and 83% at pH 4.3 and pH 6.9,respectively. The new flavin not only failed to react as a sensitizer in the dye-sensitized photopolymerization of acrylamide under some conditions, but apparently inhibited the photopolymerization by riboflavin or FMN. The new flavin more slowly underwent photolysis than FMN to some extent.
