A diluted solution of trehalose in water has been investigated by means of neutron diffraction with isotopic H/D substitution of the water hydrogens. Data have been analyzed in terms of site–site radial distribution functions, via the EPSR simulation code. This is the first time that the capabilities of this data refinement method are tested against neutron diffraction data of a complex carbohydrate molecule. A small perturbation of water hydration shell and short hydrogen bonds between trehalose oxygens and water hydrogens has been evidenced.

Abstract
A diluted solution of trehalose in water has been investigated by means of neutron diffraction with isotopic H/D substitution of the water hydrogens. Data have been analyzed in terms of site–site radial distribution functions, via the EPSR simulation code. This is the first time that the capabilities of this data refinement method are tested against neutron diffraction data of a complex carbohydrate molecule. A small perturbation of water hydration shell and short hydrogen bonds between trehalose oxygens and water hydrogens has been evidenced.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
