L-leucyl-L-proline (Leu-Pro) and its retro variant Pro-Leu may be used along with other proline dipeptides to study imprinting and chemotaxis in tetrahymena.

A novel metabonomic method based on fast liquid chromatography coupled with ion trap-time of flight mass spectrometry (UFLC/MS-IT-TOF) was applied to study the metabolic changes of plasma and urine in depression and excess fatigue rats. Principal component analysis (PCA) and
Our investigations demonstrate that proline-containing dipeptides can provoke a chemosensory response from the unicellular Tetrahymena pyriformis. The chemotactic effects of the dipeptides have a close relationship with the side chain and the lipophilicity of the amino-terminal amino acid. Comparison of
Proline-glycine, proline-leucine and proline-valine dipeptides and their retro variants were used in the experiments to study the effects of pretreatment (imprinting) in Tetrahymena, by investigating fluorescein isothiocyanate (FITC)-conjugated peptide binding. The protozoan organism could differentiate between the proline-dipeptides containing different
Dynamic capillary electrophoresis (DCE) and computer simulation of the elution profiles with the theoretical plate and the stochastic model has been applied to determine the isomerization barriers of the three dipeptides L-alanyl-L-proline, L-leucyl-L-proline, and L-phenylalanyl-L-proline. The separation of the rotational
