Conference publicationsSome aspects of structure and conformation lability of natural L-amino acids and model oligopeptidesRussia, Pushchino On the basis of semi-empirical quantum-chemical calculations the organization of the form of neutral amino acids and their zwitterions, and also of short peptides in gas phase and in water environment is discussed. A special attention is given to the role of the structural and thermodynamic factors in definition of the preferable isomeric forms of amino acids in spiral organization of single oligopeptide chains. |
