X-ray dynamical diffraction in amino acid crystals: a step towards improving structural resolution of biological moleculesviaphysical phase measurements

Year: 2017

Type: article

Abstract: In this work, experimental and data analysis procedures were developed and applied for studying amino acid crystals by means of X-ray phase measurements. The results clearly demonstrated the sensitivity of invariant triplet phases to electronic charge distribution in d-alanine crystals, providing useful information for molecular dynamics studies of intermolecular forces. The feasibility of using phase measurements to investigate radiation damage mechanisms is also discussed on experimental and theoretical grounds.
