1 spectroscopy, we have investigated cis-trans isomerism for N-acetyl, N"-methylamide derivatives of syn- and anti-5-methylproline (syn: the methyl group and carboxamide are on the same side of the proline ring, anti: on opposite sides). Proline synemin Homo sapiens
2 For Ac-syn-5-MeProNHMe, we observe about 25% cis peptide bond isomers in most solvents as is common for oligopeptides of proline. Proline synemin Homo sapiens
