| Popis: |
DFT calculations made at the B3LYP/6-31+G(d) level were used to investigate how the incorporation of a second amino acid into the backbone affects the conformational preferences of proline. Specifically, the this research studied the second amino acids L-proline and L-alanine and the trans isomerism of the peptide bonds. The lowest energy minimum has been found to have a different conformation for the two systems investigated; while the third presents a different conformation. The results obtained offer evidence of the influence of these systems on the conformational preference of proline. |
