Abstract

Cholecystokinin analogues containing N-methyl amino acids were studied by reversed-phase high-performance liquid chromatography at reduced temperatures. A reduction in temperature to - 17°C led to lower efficiency, but at the same time separations of cis and trans isomers (and some impurities) were achieved. The velocity constants for cis-trans equilibria were calculated.
