It has more than one long-lived conformational state. In the following scheme, light blue atoms are carbons, white ones are hydrogens, red are oxygens, and blue are nitrogens. In this exercise you will obtain a simplified version of the above potential energy surface, obtained in a very similar way as in the paper. From This Paper Figures, tables, and topics from this paper. Create a new directory for this exercise, and copy there the files all commented that you can download from the wiki: Larkin , Yihan Shao , Bernard R. Amino acids with hydrogen-bonding side chains have an intrinsic tendency to sample various turn conformations in aqueous solution.

From this, a grid of energies will be built, and the energy diagram Ramachandran plot will be constructed. Cheeseman , Michael J. It has more than one long-lived conformational state. Ramachandran plot for Alanine Dipeptide Alanine dipeptide is often studied in theoretical work because it is among the simplest systems to exhibit some of the important features common to biomolecules. Water-mediated conformations of the alanine dipeptide as revealed by distributed umbrella sampling simulations, quantum mechanics based calculations, and experimental data. X-ray spectroscopy of blocked alanine in water solution from supermolecular and supermolecular-continuum solvation models: Comparison of Three Chain-of-States Methods: Amino acids with hydrogen-bonding side chains have an intrinsic tendency to sample various turn conformations in aqueous solution.

The diagram represents the contour lines of the molecular energy as a function of the two dihedral angles. The number of experimental methods making it possible to determine such conformational distribution is limited.
