Summary

The1H NMR spectra of Biliverdin IXα and Mesobiliverdin XIIIα were studied in order to explain their low resolution in CDCl3/CD3OD solvent mixtures. The smallT 2 andT 1 values of these1H NMR spectra are probably due to aggregate formation promoted by the presence of the free propionic acid substituents.

Zusammenfassung

Es wurden die1H-NMR-Spektren von Biliverdin IXα und Mesobiliverdin XIIIα untersucht. In CDCl3/CD3OD-Mischungen erhält man eine schlechte Auflösung. Die niedrigenT 1-undT 2-Werte lassen sich durch eine Aggregatbildung erklären, die durch die freien Propionsäuregruppen verursacht wird.
