Abstract
The differential adsorption of the two enantiomers of the alanine molecule on the crystalline native cellulose is calculated on the basis of a semi-empirical atom—atom description of the interactions between the molecule and the surface. In contrast with quartz surfaces for which the chirality has a structural nature, the chirality for the cellulose surface is intrinsic and local. The discriminatory ratio for the diastereoisomers is calculated to be close to 1% and it could be experimentally observed.
