A model for the chiral recognition of L and D amino acids by helicoidal systems
1Departmento de Física Fundamental y Experimental, Universidad de La Laguna, 38203, Tenerife, Spain.
Abstract:
The interaction between a helix and an amino acid molecule is determined on the basis of semi-empirical potentials including Lennard-Jones, electrostatic, induction and hydrogen bond contributions. Calculations are performed for various values of the helix characteristics which schematize helicoidal polysaccharides (cellulose, cellulose derivatives⋯). The helix configuration acts as a chiral revealer as it frozes the amino acid inside its cavity. The chiral discriminatory ratio is maximum for similar sizes of the cavity and of the analyte.

Chirality
Chiral objects exhibit a sense of handedness when they interact with another chiral object. For example, our left foot can only fit in the left shoe and not in the right shoe. Achiral objects — objects that have...
