| Abstract: | A new flavin metabolite comprising approximately 5% of the total flavin of human urine was isolated and characterized using absorption and fluorescence spectra, oxidation-reduction and hydrolysis data, and ninhydrin reactions. The flavin is a derivative associated with a peptide residue in ester linkage from an amino acid carboxyl to the ribityl chain of riboflavin, probably at the 5'-terminus. |
