Abstract

Molecular mechanics calculations were performed on model linear chains of lignin and carbohydrate polymeric structures of living plants andsoil humic materials. Among possible lignin chain conformers that result from minimum-energy conformers of dimeric units, a broad regular helix may contain a carbohydrate ribbon inside itself. This structure provides an energy gain in comparison with other ways of mutual adjustment of lignin and carbohydrate polymers. Oxidation of lignin into respective humic acids sharply changes the spatial organization of the initial polymer only if it is not associated with a carbohydrate.
