A study of the cis/trans isomerism of N-acetyl-L-proline in aqueous solution by 17O n.m.r. spectroscopy

Abstract

The cis and trans isomers of both the enriched carboxy and amide groups of N-acetyl-L-proline can be observed by 17O n.m.r. spectroscopy and are shown in each case to give parallel pH titration curves.
